Answer

To answer the question "Prothorax contains which of the following components?" we need to analyze the components associated with the prothorax of a cockroach.

### Step-by-Step Solution:

1. **Understanding the Structure of a Cockroach**:
- The cockroach body is divided into three main segments: the head, thorax, and abdomen.
- The thorax is further divided into three parts: prothorax, mesothorax, and metathorax.

2. **Identifying the Components of the Prothorax**:
- The prothorax is the first segment of the thorax and does not contain any wings.
- The mesothorax contains the forewings, and the metathorax contains the hindwings.

3. **Analyzing the Options**:
- **Option 1: Four wings** - This is incorrect because the prothorax does not have wings.
- **Option 2: First pair of thoracic spiracles** - This is also incorrect because spiracles are not located on the thorax; they are found on the abdomen.
- **Option 3: Prolegs** - This is correct as each segment of the thorax, including the prothorax, contains a pair of legs known as prolegs.
- **Option 4: All of these** - This is incorrect as not all the options are true.

4. **Conclusion**:
- The correct answer is **Option 3: Prolegs**.
