Options

A. Spermathecae

C. Spermathecal apertures
D. Egg capsule

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about what spermatophores are. We need to analyze the given options to determine the correct definition.

2. **Analyzing Option A - Spermatheca**:
- The term "spermatheca" refers to a structure found in female cockroaches that is involved in receiving and storing sperm.
- Since spermatophores are not the same as spermatheca, this option is incorrect.

3. **Analyzing Option B - Packets of Sperm**:
- Spermatophores are indeed defined as packets or capsules that contain sperm.
- This aligns with the definition of spermatophores, making this option correct.

4. **Analyzing Option C - Spermathecal Apertures**:
- Spermathecal apertures are openings that allow sperm to enter the spermatheca.
- This term is related to the spermatheca and does not define spermatophores, so this option is incorrect.

5. **Analyzing Option D - Egg Capsule**:
- Egg capsules are structures in which female cockroaches release their eggs.
- This is unrelated to sperm and therefore is also incorrect.

6. **Conclusion**: After analyzing all the options, the correct answer is that spermatophores are "packets of sperm."

**Final Answer**: Spermatophores are packets of sperm.
