## **Core Concept**
Medical termination of pregnancy (MTP) refers to the intentional ending of a pregnancy before the fetus reaches viability. The Medical Termination of Pregnancy Act of 1971 in India specifies conditions under which a pregnancy can be terminated. The gestation period is a critical factor in determining the method and legality of pregnancy termination.

## **Why the Correct Answer is Right**
The Medical Termination of Pregnancy (MTP) Act in India allows for the termination of pregnancy by a registered medical practitioner if the gestation period is less than 20 weeks. This timeframe is crucial because it allows for medical termination under certain conditions specified by the Act, such as risk to the mother's life, physical or mental health, or in cases of rape. Beyond 20 weeks, termination is generally not permitted except under very rare circumstances and usually requires a more complex legal and medical evaluation.

## **Why Each Wrong Option is Incorrect**
- **Option A:** 12 weeks. While termination can indeed be done before 12 weeks under the MTP Act, the question asks for the upper limit less than which termination can be done by a registered medical practitioner. Therefore, this option is too restrictive.
- **Option B:** 15 weeks. This is still within the timeframe where termination could potentially be considered under the Act but does not represent the maximum limit.
- **Option D:** 24 weeks. Although the MTP Act was amended in 2021 to allow for termination up to 24 weeks under specific conditions, the general provision still emphasizes less than 20 weeks for a straightforward registered medical practitioner's decision.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that while the general limit for medical termination of pregnancy by a registered medical practitioner is less than 20 weeks, amendments to the MTP Act allow for pregnancies up to 24 weeks to be terminated under certain conditions. However, these conditions require more stringent approval processes.

## **Correct Answer:** . 20 weeks.
