Let’s evaluate the given statements with respect to the Medical Termination of Pregnancy (MTP) Act, 2017:
(A) Approximately 20% of the conceived pregnancies undergo MTP globally in a year: This is correct. According to various studies, approximately 20% of pregnancies worldwide are terminated each year, either due to medical, social, or other reasons.
(B) MTP is legalized in India up to four months unconditionally: This is incorrect. Under the MTP Act, 2017, MTP is allowed up to 24 weeks, but not unconditionally. The law requires the approval of medical practitioners, and specific conditions must be met for pregnancies beyond 20 weeks. Additionally, the reason for termination needs to be medically justifiable (e.g., fetal abnormalities, risk to the mother's health).
(C) Amniocentesis is mandatory before performing MTP: This is incorrect. Amniocentesis is not a mandatory procedure for performing an MTP. The decision for an MTP is based on medical evaluation, and amniocentesis may only be performed if required for diagnosing certain fetal conditions.
(D) MTPs are considered relatively safe up to 12 weeks of pregnancy: This is correct. MTP is considered relatively safe up to 12 weeks of pregnancy, with lower risk for complications such as hemorrhage or infection compared to later stages.
Thus, the correct statements are (A) and (D), making the correct answer:
(4) (A) and (D) only.
Statement (A) is correct as approximately $20\%$ of conceived pregnancies globally undergo MTP each year. Statement (D) is also correct, as MTPs are considered relatively safe within the first 12 weeks. Statement (B) is incorrect because MTP in India is not unconditionally allowed up to four months; it is regulated and allowed under specific conditions. Statement (C) is also incorrect because amniocentesis is not mandatory before performing MTP.
