Given below are two statements, one labeled as Assertion (A) and the other labeled as Reason (R). **Assertion (A):** Plants in the semi-arid thorn forests of Rajasthan, such as Acacia and Euphorbia, have highly reduced leaves or leaves modified into spines. **Reason (R):** The reduction of leaf surface area and modification into spines is a physiological adaptation to minimize water loss through transpiration under high temperature and low humidity conditions. In the context of the above statements, which of the following is correct?

Options:

• A: Both (A) and (R) are true and (R) is the correct explanation of (A).
• B: Both (A) and (R) are true but (R) is not the correct explanation of (A).
• C: (A) is true but (R) is false.
• D: (A) is false but (R) is true.
