Options

A. (i) and (iii)
B. (i) and (ii)
C. (ii) and (iii)
D. (iii) and (iv)

Explanation

To determine which of the statements are correct, let's analyze each statement step by step:

### Step-by-Step Solution:

1. **Statement (i): Medical termination of pregnancy (MTP) during the first trimester is generally safe.**
- **Analysis:** Medical termination of pregnancy is considered safe during the first trimester (up to 12 weeks) because the fetus is not yet intimately attached to the maternal tissues. This allows for safer termination methods, either through medication or surgical procedures.
- **Conclusion:** This statement is **correct**.

2. **Statement (ii): Generally, chances of conception are nil until the mother breastfeeds the infant up to two years.**
- **Analysis:** While breastfeeding can act as a natural contraceptive method (known as lactational amenorrhea), this is only effective for about six months postpartum. After six months, the chances of conception can increase, and by the time the infant is two years old, there are significant chances of conception even if breastfeeding continues.
- **Conclusion:** This statement is **incorrect**.

3. **Statement (iii): Intrauterine devices like Copper-T are effective contraceptives.**
- **Analysis:** Copper-T is an intrauterine device (IUD) that is highly effective as a contraceptive method. It can remain in place for several years (up to 10 years) and is reversible, meaning that fertility returns quickly after its removal.
- **Conclusion:** This statement is **correct**.

4. **Statement (iv): Contraceptive pills may be taken up to one week after coitus to prevent conception.**
- **Analysis:** Emergency contraceptive pills are most effective when taken within 72 hours (3 days) after unprotected intercourse. They can still be effective up to 120 hours (5 days), but their efficacy decreases significantly after that. Taking them one week (7 days) after coitus is not effective.
- **Conclusion:** This statement is **incorrect**.

### Final Answer:
The two correct statements are:
- (i) Medical termination of pregnancy (MTP) during the first trimester is generally safe.
- (iii) Intrauterine devices like Copper-T are effective contraceptives.
