- D Cu-375 (5 years)
Correct answer: A. IUCD-375 (5 years) and Cu T-380A (10 years), with Cu T-380A being superior
Explanation
India's national programme provides both Cu-375 (approved for 5 years) and Cu T-380A (approved for 10 years, also licensed up to 12 years in some countries). The T-380A has a Pearl Index < 0.8 and higher copper surface area (380 mm²) offering superior contraceptive efficacy and longer approved duration compared to Cu-375 (375 mm²). The T-380A is now the preferred IUCD in India's programme.
