Mechanism Of Hormone Action

To solve this problem, let's carefully match the items in List I with the correct items in List II based on their characteristics:

1. Non-medicated IUD: These are devices that do not release any medication. The Lipper loop is a type of non-medicated IUD. Hence, A matches with III.
2. Copper releasing IUD: These IUDs release copper ions which help in birth control. The Multiload 375 is a well-known copper releasing IUD. Hence, B matches with I.
3. Hormone releasing IUD: These release hormones, for example using levonorgestrel. LNG-20 is a type of hormone releasing IUD. Hence, C matches with IV.
4. Implants: These are devices inserted under the skin that release hormones such as progestogens. Hence, D matches with II.

Therefore, the correct option is A-III, B-I, C-IV, D-II.
