Assertion [A]: For toxicity testing, transgenic animals are made to carry genes which make them more sensitive to toxic substance.
Reason [R]: Transgenic animals are exposed to toxic substances to study the effect of these toxins.

• A. Both A and R are correct and R explains A
• B. Both A and R are correct and R does not explain A
• C. A is correct but R is incorrect
• D. Both A and R are incorrect

The correct option is B Both A and R are correct and R does not explain A

Transgenic animals are used to study the toxicity effects of certain chemicals. These animals are made to carry genes which make them more sensitive to toxic substances. The exposure to these toxins enable researchers to study their effects on the organisms and help formulate regulations and safe dosage levels.
