Eggs of cockroach are 

Options

A. Telolecithal
B. Isolecithal
C. Centrolecithal
D. Alecithal

Answer

To determine the type of eggs produced by cockroaches, we need to analyze the characteristics of different types of eggs based on yolk distribution. Here’s a step-by-step breakdown of the solution:

### Step 1: Understanding Egg Types
- **Yolk** is a nutrient-rich substance found in eggs that provides nourishment to the developing embryo. The distribution and amount of yolk in eggs can vary, leading to different classifications of eggs.

### Step 2: Classifying Egg Types
- The four types of eggs mentioned are:
1. **Telolacethyl**: Yolk is concentrated at one end of the egg.
2. **Isolacethyl**: Yolk is uniformly distributed throughout the egg.
3. **Centrolacethyl**: Yolk is concentrated at the center of the egg.
4. **Allicethyl**: Yolkless eggs.

### Step 3: Identifying the Correct Type for Cockroaches
- Cockroaches, being arthropods, produce eggs for reproduction. The type of eggs they produce is characterized by the concentration of yolk.
- Cockroaches specifically produce **centrolacethyl eggs**, where the yolk is concentrated at the center of the egg.

### Step 4: Eliminating Incorrect Options
- **Allicethyl** (yolkless) is not applicable to cockroaches.
- **Isolacethyl** (uniform yolk distribution) does not represent cockroach eggs.
- **Telolacethyl** (yolk at one end) is also not the type produced by cockroaches.

### Conclusion
- The correct answer is **centrolacethyl** eggs, as this is the type produced by cockroaches.

### Final Answer
- Cockroach eggs are **centrolacethyl**.
