Answer

To answer the question about the first pair of wings of a cockroach, let's break it down step by step:

### Step 1: Understand the Anatomy of Cockroach Wings
Cockroaches have two pairs of wings. Each pair of wings is attached to different segments of the thorax.

### Step 2: Identify the Wing Types
- The **first pair of wings** is known as the **Tegmina** (or forewings).
- The **second pair of wings** is known as the **hindwings**.

### Step 3: Determine the Attachment Points
- The **Tegmina** (first pair of wings) are attached to the **mesothorax**.
- The **hindwings** are attached to the **metathorax**.

### Step 4: Analyze the Options
Given the options:
1. Tegmina attached to mesothorax
2. Elytra attached to metathorax
3. Tegmina attached to prothorax
4. Tegmina attached to metathorax

From the analysis:
- Option 1 is correct: **Tegmina are attached to the mesothorax**.
- Option 2 is incorrect because Elytra (another name for Tegmina) are not attached to the metathorax.
- Option 3 is incorrect because Tegmina are not attached to the prothorax.
- Option 4 is incorrect because Tegmina are not attached to the metathorax.

### Conclusion
The first pair of wings of a cockroach is the **Tegmina**, which are attached to the **mesothorax**.
