Show Hint
Remember:
- Deer have Antlers (DA) $\rightarrow$ temporary, branched, shed annually.

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
This question tests the anatomical distinction between horns (found in the family Bovidae, such as antelopes) and antlers (found in the family Cervidae, such as deer).
Step 2: Detailed Explanation:
Let us evaluate both statements:
- Statement (I): This statement is anatomically backward. Antelopes (belonging to the family Bovidae) possess horns. Horns are permanent, unbranched structures composed of a bony core covered by a keratinized epidermal sheath. Deer (belonging to the family Cervidae) possess antlers. Antlers are branched, temporary structures composed entirely of bone. Thus, Statement (I) is false.
- Statement (II): Horns are permanent structures that grow continuously throughout the animal's life; if they are broken, they do not grow back. In contrast, antlers are temporary structures that are shed annually (typically after the breeding season) and regrown the following year. This cyclic regrowth is regulated by testosterone levels. Thus, Statement (II) is true.
Therefore, Statement (I) is false but Statement (II) is true.
Step 3: Final Answer:
Statement (I) is false but Statement (II) is true, which corresponds to option (D).
