Understanding +4 | -1

Given below are two statements. One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) Photochemical smog causes cracking of rubber.
Reason (R) Presence of ozone, nitric oxide, acrolein, formaldehyde and peroxyacetyl nitrate in photochemical smog makes it oxidising.
Choose the most appropriate answer from the options given below.

View answer and explanation

Correct option: B

Both (A) and (R) are true and (R) is the correct explanation of (A).

Option B is correct because both the assertion and reason are true, and the reason correctly explains why photochemical smog causes cracking of rubber due to its oxidizing nature.
