Options

A. (a) homolecithal
B. (b) telolecithal
C. (c) centrolecithal
D. (d) mesolecithal

Answer

**Step-by-Step Solution:**

1. **Understanding Egg Types:** The question asks about the type of eggs produced by cockroaches. To answer this, we need to understand the classification of eggs based on the distribution of yolk.

2. **Types of Eggs Based on Yolk Distribution:**
- **Homolecithal Eggs:** These eggs have a small amount of yolk that is uniformly distributed throughout the egg. An example is found in sea urchins.
- **Telolecithal Eggs:** In these eggs, the yolk is concentrated at one pole. Birds are a common example of this type.
- **Centrolecithal Eggs:** These eggs have a large amount of yolk that is concentrated in the center of the egg. This type is characteristic of many insects, including cockroaches.
- **Mesolecithal Eggs:** These eggs contain a moderate amount of yolk, which is distributed more evenly than in telolecithal eggs. Fish are examples of this type.

3. **Identifying the Correct Type for Cockroaches:** Since cockroaches are insects, we look for the type of egg that corresponds to insects. The centrolecithal egg type is the one that fits this description, as it has a large amount of yolk concentrated in the center.

4. **Conclusion:** Based on the classification and the characteristics of cockroach eggs, we conclude that the eggs of cockroaches are **centrolecithal eggs**.

**Final Answer:** The eggs of cockroaches are centrolecithal.
