Given below are two statements : One is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A) : Both wind and water pollinated flowers are not very colourful and do not produce nectar.
Reason (R) : The flowers produce enormous amount of pollen grains in wind and water pollinated flowers.

In the light of the above statements, choose the correct answer from the options given below:

The assertion states that “Both wind‑ and water��pollinated flowers are not very colourful and do not produce nectar.” This is accurate because these plants do not rely on animal visitors for pollination; therefore they have no evolutionary pressure to develop bright colours or nectar rewards.

The reason claims that “The flowers produce enormous amounts of pollen grains in wind and water pollinated flowers.” This is also correct. Anemophilous (wind‑pollinated) and hydrophilous (water‑pollinated) species typically release large quantities of lightweight pollen to increase the chance of successful transfer.

Although both statements are true, the reason does not explain the assertion. The lack of colour and nectar is a consequence of the pollination mechanism (no need to attract pollinators), not a direct result of the volume of pollen produced. Hence, the reason is unrelated to the cause of the traits described in the assertion.

Consequently, the correct option is: Both A and R are true but R is NOT the correct explanation of A.
