Which of the following contraceptive is an injectable form of the "birth control pill hormones" that prevent ovulation ?

Options

A. Norplant
B. Depo-Provera
C. Saheli
D. Mala-D

Answer

To determine which contraceptive is an injectable form of the "birth control pill hormones" that prevent ovulation, we can analyze the options provided:

1. **Norplant**: This is an implantable contraceptive, not an injectable form. It is inserted under the skin and releases hormones to prevent ovulation.

2. **Depo-Provera**: This is an injectable contraceptive. It is administered as an intramuscular injection and contains progestin, a hormone that prevents ovulation. It is typically given every three months and also thickens cervical mucus to prevent sperm penetration.

3. **Saheli**: This is an oral contraceptive pill, taken once a week. It is a non-steroidal pill and does not come in an injectable form.

4. **Maladi**: This is also an oral contraceptive pill that inhibits ovulation but, like Saheli, it is not an injectable form.

Based on this analysis, the correct answer is **Depo-Provera** as it is the only injectable contraceptive among the options that prevents ovulation.

### Steps:
1. **Identify the options given**: Norplant, Depo-Provera, Saheli, Maladi.
2. **Evaluate each option**:
- Norplant: Implantable, not injectable.
- Depo-Provera: Injectable, contains progestin, prevents ovulation.
- Saheli: Oral contraceptive, not injectable.
- Maladi: Oral contraceptive, not injectable.
3. **Determine which option fits the criteria**: Depo-Provera is the only injectable contraceptive that prevents ovulation.
4. **Conclude the answer**: The correct answer is Depo-Provera.
