C. 'Saheli' is once a month pill.
D. Government of India has legalized MTP act in 1981

Answer

To solve the question "Select the correct statement," we will analyze each of the provided options one by one.

### Step-by-Step Solution:

1. **Evaluate Option A**: "Population of India has crossed 1 million in May 2000."
- This statement is incorrect. The population of India crossed **1 billion** (not 1 million) in May 2000.

2. **Evaluate Option B**: "Cervical caps and bolts both are barrier methods of contraception."
- This statement is correct. Both cervical caps and condoms (often referred to as "bolts" in some contexts) are indeed barrier methods of contraception, which prevent sperm from reaching the egg.

3. **Evaluate Option C**: "Saheli is a once a month pill."
- This statement is incorrect. Saheli is a contraceptive pill that is taken **once a week**, not once a month.

4. **Evaluate Option D**: "Government of India has legalized MTP Act in 1981."
- This statement is also incorrect. The Medical Termination of Pregnancy (MTP) Act was legalized in **1971**, not 1981. This act provides a legal framework for the termination of pregnancies under certain conditions.

### Conclusion:
After evaluating all the options, the only correct statement is **Option B**: "Cervical caps and bolts both are barrier methods of contraception."
