Option D (Peptidoglycans) is correct because many antibiotics target the synthesis of peptidoglycans, which are essential components of bacterial cell walls.

Option D (Helper T-Cells) is correct because HIV primarily infects and destroys Helper T-Cells (CD4+ T-cells).

Option B (Myelomas) is correct because myelomas are cancerous plasma cells, which are often obtained from cancerous tumors.

Option C (Allergy) is correct because antihistamines, adrenaline, and steroids are commonly used to treat allergic reactions.

Option A (Tetanus, Typhoid, Pneumonia) is correct because all three diseases are caused by bacteria.

Option D (Oxytetracycline) is correct because oxytetracycline is often used as a feed additive for pigs to promote growth and prevent disease.

Option A (Both Statement-I and Statement-II are correct) is correct because allergy is an immune disorder and is specific to an individual.

Option C is correct because AIDS involves both the destruction of the immune system and the development of opportunistic infections and related symptoms.

Option D is correct because antibodies separated from serum are not homogenous, and monoclonal antibodies are homogenous immunological reagents, making both statements incorrect.

The correct answer is B (second world war) because Penicillin was widely used during the Second World War to treat infections.

Option D (IgE and Histamine) is correct because IgE antibodies and histamine are key players in allergic reactions.

Option B (Tuberculosis and pneumonia) is correct because both tuberculosis and some types of pneumonia are bacterial infections that can be treated with antibiotics.

Option D is correct because Cancer, tuberculosis, and tetanus are not all primarily parasitic diseases, unlike the other options.

Option B (Both statements A and B are correct) is correct because both statements accurately describe aspects of allergic reactions and their treatment.

Option B (If both Assertion and Reason are true but Reason is not the correct explanation of Assertion) is correct because artificially acquired passive immunity involves introducing antibodies or lymphocytes, and bone marrow transplants address genetic deficiencies but are not an example of passive immunity.

Option D is correct because both statements accurately describe the roles of histamine and the evolution of memory-based immunity.

Option D (I, II and III) is correct because all three statements accurately describe opioids and heroin.

Option A is correct because both the assertion and the reason are true, and the reason correctly explains why diseases like polio, diphtheria, pneumonia, and tetanus have been controlled.

Option A is correct because perspiration is a physiological symptom of anxiety, while distorted thoughts and strong reactions to stress are psychological symptoms, and increased heart rate is also a physiological symptom.

Option C (If assertion is true but reason is false) is correct because Killer T-cells participate in Cell-Mediated Immunity (CMI), but they can lyse both viral-infected cells and tumor cells.

The correct answer is D (Statements A and B are correct; Statement C is incorrect) because HIV is an oncogenic virus, non-cancerous cells exhibit contact inhibition, and malignant tumors do show metastasis and angiogenesis.

Option C (Willen Einthoven) is correct because Willen Einthoven developed the electrocardiograph (ECG), a device used to measure the electrical activity of the heart.

Option C (Minuta form) is correct because the minuta form of Entamoeba histolytica is the non-invasive, non-motile, and non-feeding encysted stage that is infectious.

Option D is correct because all the listed factors (sensitivity to the environment, protected early environment, and modern lifestyle) contribute to the increased prevalence of allergies and asthma in metropolitan cities.
