Answer

To solve the question regarding the incorrect statement about the head of the cockroach, we will analyze each of the four statements provided.

### Step-by-Step Solution:

1. **Statement Analysis**:
- **Statement 1**: "It is Hypognathus."
- **Explanation**: This statement is true. The head of the cockroach is indeed hypognathous, meaning it is oriented such that it lies perpendicular to the body axis.

2. **Statement 2**: "It is formed by the fusion of six embryonic segments."
- **Explanation**: This statement is also true. The head of the cockroach is formed from the fusion of six embryonic segments, which contributes to its structure and flexibility.

3. **Statement 3**: "The head bears appendages forming biting and chewing type of mouth parts."
- **Explanation**: This statement is true as well. The head of the cockroach has various mouthparts, including the labrum, labium, mandibles, maxillae, and hypopharynx, which function for biting and chewing.

4. **Statement 4**: "A pair of broad antenna arise from membranous sockets lying in the front of eyes."
- **Explanation**: This statement is incorrect. The antennae of the cockroach are not broad; they are long and thread-like, which allows for better sensory perception.

### Conclusion:
The incorrect statement regarding the head of the cockroach is **Statement 4**.

### Final Answer:
**D** - A pair of broad antenna arise from membranous sockets lying in the front of eyes.
