C. Aestivation
D. Rejuvenation

Correct Answer:

Option B – Hibernation

Explanation

Xeromorphic describes the structural modifications of certain plants (xerophytes) that enable them to reduce water loss, particularly from their leaves and stems.

Hibernation is a state of inactivity and metabolic depression in endotherms. Hibernation refers to a season of heterothermy characterized by low body temperature, slow breathing and heart rate, and low metabolic rate. The state of inactivity and a low metabolic process performed by the animals during the winters is known as Hibernation. It is also known as winter sleep.
