B. Copper T
C. Saheli
D. Norplant

Answer

To solve the question, "Which of the contraceptive release mineral ions to inhibit the motility of a sperm?", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Options**: The options provided are condoms, Copper-T, Saheli, and Norplant.

2. **Analyze Each Option**:
- **Condoms**: These are barrier methods that prevent sperm from meeting the ovum. They do not release any mineral ions. Therefore, this option is incorrect.
- **Copper-T**: This is an intrauterine device (IUD) that releases mineral ions, specifically copper ions, which create an environment that is toxic to sperm and inhibits their motility. This option is likely correct.
- **Saheli**: This is an oral contraceptive pill that does not release mineral ions but works by hormonal regulation. Therefore, this option is incorrect.
- **Norplant**: This method involves the release of hormones (Levonorgestrel) and does not involve the release of mineral ions. Therefore, this option is also incorrect.

3. **Conclusion**: The only contraceptive method listed that releases mineral ions to inhibit the motility of sperm is **Copper-T**.

### Final Answer:
The correct answer is **Copper-T**.
