| List-I | List-II |
|---|---|
| A. Progestasert | I. Barrier made of rubber used by females |
| B. Multiload 375 | II. Oral contraceptive |
| C. Diaphragm | III. Hormone releasing IUD |
| D. Saheli | IV. Copper releasing IUD |
Solution
Core Logic
Let's classify the contraceptive devices based on their mechanism:
- Progestasert (A) and LNG-20 are Hormone-releasing IUDs (A-III).
- Multiload 375 (B), along with CuT and Cu7, are Copper-releasing IUDs (B-IV).
- Diaphragms (C), cervical caps, and vaults are rubber barriers inserted into the female reproductive tract to cover the cervix (C-I).
- Saheli (D) is a non-steroidal oral contraceptive pill designed for females (D-II).
Step 1: Final Conclusion
The correct matches are A(III), B(IV), C(I), D(II).
Pattern Recognition
Saheli is famously the oral pill from CDRI (D-II). Progestasert has "progest" in its name, implying hormone (A-III). Multiload 375 is a standard Cu IUD (B-IV).
