Covering of spermatophore in Cockroach is formed by

Options

A. Mushroom gland
B. Conglabate gland
C. Phallic gland
D. B and C

Answer

To solve the question regarding the covering of the spermatophore in cockroaches, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks about the covering of the spermatophore in cockroaches. A spermatophore is a capsule or packet containing sperm.

2. **Identify the Options**: The options provided are:
- Option 1: Mushroom gland
- Option 2: Conglobate gland
- Option 3: Phallic gland
- Option 4: BNC (presumably referring to a specific gland)

3. **Recall Relevant Biological Knowledge**: In cockroaches, the spermatophore is formed during reproduction, and its covering is produced by specific glands.

4. **Determine the Glands Involved**: The covering of the spermatophore is formed by the secretions of two glands:
- **Conglobate gland**
- **Phallic gland**

5. **Analyze the Options**:
- The mushroom gland is not involved in the formation of the spermatophore covering.
- The conglobate gland and phallic gland are both involved in forming the covering.

6. **Select the Correct Answer**: Since both the conglobate gland and phallic gland contribute to the covering of the spermatophore, the correct answer is:
- **Option 2 (Conglobate gland) and Option 3 (Phallic gland)**, which can be summarized as **B and C**.

### Final Answer:
The covering of the spermatophore in cockroaches is formed by the **conglobate gland and phallic gland**.
