Which of the above statements are correct?

Assertion (A): Genetic modification of organisms can have unpredictable results when they are introduced into the ecosystem.
Reason (R): The Indian Government has set up organisations such as GEAC, which will make decisions regarding the validity of GM research and the safety of introducing GM organisms for public services.

_______ refers to the use of bio-resources by multinational companies and other organizations without proper authorization from the counties and people concerned without compensatory payment. Fill the blank with a suitable option
