Solution

The correct option is B Both assertion and reason are true but reason is not the correct explanation of assertion
Vernalisation is the process of inducing flowering in plants by exposing them to low temperature. The requirement of low temperature by some plants can be replaced by the use of gibberellins.

ABA hormone inhibits plant growth and metabolism. It plays an important role in seed development and maturation.
