**Core Concept**
The Pre-Natal Diagnostic Techniques (Regulation and Prevention of Misuse) Act (PNDT Act) 1994 is a legislation aimed at preventing the misuse of prenatal diagnostic techniques, such as ultrasound and amniocentesis, for sex-selective abortion.

**Why the Correct Answer is Right**
The PNDT Act 1994 was enacted to prevent the misuse of prenatal diagnostic techniques, particularly ultrasound, to determine the sex of the fetus, leading to sex-selective abortion. This act makes it mandatory for all ultrasound machines to be registered and for the operators to undergo training. It also establishes a three-member committee to inspect and verify the records of ultrasound machines in every district. The act has been amended several times to strengthen its provisions.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is not relevant to the PNDT Act 1994, which deals specifically with prenatal diagnostic techniques and sex-selective abortion.
**Option B:** This option is incorrect because the Medical Termination of Pregnancy (MTP) Act 1971 deals with the termination of pregnancy, not prenatal diagnostic techniques.
**Option C:** This option is not a correct statement about the PNDT Act 1994.

**Clinical Pearl / High-Yield Fact**
It is essential for healthcare providers to be aware of the PNDT Act 1994 and its provisions to prevent the misuse of prenatal diagnostic techniques and to promote a safe and equitable approach to reproductive healthcare.

**Correct Answer:** D.
