Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Pollen grains can be well preserved and used as microfossils due to the presence of sporopollenin which contributes to the formation of its outer layer exine and is the most stable and non-degraded chemical.
In certain places on pollen grains exine is absent and they have a thick layer of intine at these places known as germ pore through which pollen tube emerges.
So, the correct option is 'Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion'.
