Solution

The correct option is B LNG-20
LNG-20 is an intrauterine device (IUD) containing levonorgestrel, a synthetic steroid hormone similar to progesterone.

Cu-T is a copper releasing IUD. It constantly releases a small amount of copper into the uterus. These ions suppress sperm motility and the fertilising capacity of sperms.

Lippes loop, a non-medicated IUD, is made of inert plastic in a double S-shape. It can be inserted for long periods. It suppresses sperm motility and the fertilising capacity of sperms because of being impregnated with barium sulphate.
