Answer

To solve the question regarding effective emergency contraceptives that can be used to avoid possible pregnancy due to rape if administered within 72 hours, we will analyze each option provided:

### Step-by-Step Solution:

1. **Understanding Emergency Contraceptives**:
- Emergency contraceptives are methods used to prevent pregnancy after unprotected intercourse or contraceptive failure. They are most effective when taken within a specific time frame, typically within 72 hours.

2. **Option A: Administration of Progestogens**:
- Progestogens can inhibit ovulation, change the quality of cervical mucus, and alter the uterine lining. They are effective in preventing pregnancy if taken within the specified time frame.

3. **Option B: Progestogen - Estrogen Combination**:
- This combination also works by inhibiting ovulation, altering the uterine lining to prevent implantation, and changing cervical mucus to hinder sperm movement. It is effective as an emergency contraceptive.

4. **Option C: IUDs (Intrauterine Devices)**:
- IUDs can be inserted within 72 hours after unprotected intercourse. They work by preventing fertilization and implantation, making them a highly effective emergency contraceptive method.

5. **Option D: Condoms**:
- Condoms are used during sexual intercourse to prevent sperm from entering the vagina. However, they cannot be used as an emergency contraceptive after the fact, as they do not prevent pregnancy once intercourse has occurred.

6. **Conclusion**:
- Based on the analysis, the effective emergency contraceptives that can be used within 72 hours include:
- A. Administration of progestogens
- B. Progestogen - estrogen combination
- C. IUDs

### Final Answer:
The correct options are A (Administration of progestogens), B (Progestogen - estrogen combination), and C (IUDs).
