(a) Autogamy
(b) Neoteny
(c) Autophagy
(d) Autotomy

Options

A. Autogamy
B. Neoteny
C. Autophagy
D. Autotomy

Answer

To solve the question regarding the ability of starfishes to break off their arms, we can analyze the options provided:

1. **Understanding the Question**: The question asks about a specific ability of starfishes, which involves breaking off their arms. We need to identify the correct term that describes this phenomenon.

2. **Evaluating the Options**:
- **(a) Autogamy**: This term refers to self-fertilization in organisms. It does not relate to the physical ability of an organism to shed body parts.
- **(b) Neoteny**: This refers to the retention of juvenile features in the adult stage of an organism. It is not related to the shedding of limbs.
- **(c) Autophagy**: This is a process where cells degrade and recycle their components. It does not pertain to the physical act of shedding limbs.
- **(d) Autotomy**: This term specifically describes the ability of an organism to deliberately shed a part of its body, typically as a defense mechanism to escape predators.

3. **Identifying the Correct Answer**: Given the definitions, option (d) Autotomy is the correct answer. This behavior allows starfishes to escape from predators by sacrificing part of their body, which can later regenerate.

4. **Conclusion**: The ability of starfishes to break off their arms is an example of autotomy.

### Final Answer: (d) Autotomy
