Given below are two statements, one labelled Assertion (A) and the other Reason (R). Choose the correct answer.
Assertion (A):In vitro testing forms the basis for hazard identification.
Reason (R):In vitro studies are performed within the same biological entities.
ABoth A and R are correct and R is the correct explanation of A
BBoth A and R are correct but R is not the correct explanation of A
CA is correct but R is not correct ✓ Correct
DA is not correct but R is correct
Correct answer: (C) A is correct but R is not correct
Explanation
In vitro testing does underpin hazard identification, but the reason misdefines what in vitro means.
Assertion is correct because in vitro tests give early data used to flag potential hazards.
Reason is incorrect because in vitro means outside the living body, in glass or culture, not within the same biological entity.
In vitro work uses isolated cells, tissues or biochemical systems in the laboratory.
Testing within a living organism is instead called in vivo study.
In vitro methods reduce reliance on whole-animal testing.
