Options

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

Explanation

To determine which statements are correct, let's analyze each statement one by one:

1. **Statement (i)**: "India's first test tube baby's name is Kum Harsha."
- This statement is **correct**. India's first test-tube baby was indeed named Kum Harsha.

2. **Statement (ii)**: "Inability to conceive or produce children even after 2 years of unprotected sexual cohabitation is called infertility."
- This statement is also **correct**. Infertility is defined as the inability to conceive after one year of unprotected sexual intercourse, but the statement specifies two years, which still falls under the definition of infertility.

3. **Statement (iii)**: "Surgical method of contraception prevents gamete formation."
- This statement is **incorrect**. Surgical methods of contraception, such as vasectomy and tubectomy, prevent the transfer of gametes (sperm and eggs) but do not prevent their formation. The formation of gametes occurs in the reproductive organs regardless of whether they are transferred.

4. **Statement (iv)**: "MTPs are relatively safe up to 12 weeks of pregnancy."
- This statement is **correct**. Medical Termination of Pregnancy (MTP) is generally considered safe up to 12 weeks of gestation.

Now, summarizing the analysis:
- Statements (i), (ii), and (iv) are correct.
- Statement (iii) is incorrect.

Thus, the correct options are **1, 2, and 4**.

### Final Answer:
The correct statements are: **(i), (ii), and (iv)**.
