Answer 1

The correct option is A

Assertion is True, Reason is True; Reason is a correct explanation for Assertion.

Correct option is (a).

Assertion Statement:

1. Changes in organisms' structure and functions in the course of their lifespan are called acquired characteristics.
2. Acquired characters are not passed to the next generations.
3. So the assertion is true.

Reason Statement:

1. Acquired characteristics are the change in behaviour or structure of the individual.
2. These changes are related to somatic cells, so they are not passed to the next generation.
3. Changes that occur in germ cells are passed them to the next generation.
4. Acquired characters are noninheritable because these characters generally affect the somatic cells, and it is the germ cells that are passed on to the next generation.
5. So the reason is false.

Final Answer: Assertion is True, Reason is True; Reason is a correct explanation for Assertion.
