B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

Text Solution

Verified by Experts

The correct Answer is:
A
The chief function of the sclerenchymatous fibres in the plant is to give mechanical strength and save the plant from the various stresses and strains of the environmental factors, e.g., strong wind. Their presence in the leaf gives it rigidity and prevents it from collapsing. Their presence on the surface of seeds and fruits may help in dispersal by wind.
