**Core Concept**
The Medical Termination of Pregnancy (MTP) Act in India regulates the termination of pregnancy, allowing for legal abortion under specific circumstances. The Act has undergone amendments to expand the gestational limit for MTP.

**Why the Correct Answer is Right**
The MTP Act allows for abortion before the gestation of 20 weeks. This is because the Act considers the moral, social, and medical implications of abortion at different stages of pregnancy. The 20-week limit is a compromise between the rights of the mother and the potential life of the fetus. Prior to this amendment, the gestational limit was 12 weeks. The expansion of the gestational limit to 20 weeks acknowledges the complexities of pregnancy and the need for more time to consider options.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because there is no specific gestational limit mentioned for MTP in the Act. The Act outlines specific criteria for MTP, including the duration of pregnancy, but does not provide a specific limit.
**Option B:** This option is incorrect because there is no evidence to support the claim that the gestational limit for MTP is 24 weeks. While some countries have a gestational limit of 24 weeks, this is not the case in India.
**Option C:** This option is incorrect because there is no specific gestational limit mentioned for MTP in the Act. The Act outlines specific criteria for MTP, including the duration of pregnancy, but does not provide a specific limit.

**Clinical Pearl / High-Yield Fact**
The MTP Act has undergone several amendments to expand the gestational limit for MTP, acknowledging the complexities of pregnancy and the need for more time to consider options. It is essential for healthcare providers to be aware of the current regulations and guidelines for MTP in India.

**Correct Answer: C. 20 weeks.**
