B.Root system degradation and leaf shedding

Explanation:

Droughts cause a significant shortage of water, which directly affects plant life. During periods of prolonged water scarcity, plants often undergo stress responses, such as:

1. Root system degradation: With limited water availability, roots may fail to grow properly or may degrade as the plant tries to conserve energy and resources.

2. Leaf shedding: In response to water scarcity, many plants shed their leaves to reduce water loss through transpiration, which is a common survival strategy.

Here’s why the other options are less accurate:

A. Increased photosynthesis and growth: Droughts typically reduce, not increase, photosynthesis and growth because ...
