Answer 1

The correct option is D

Both B and C

LNG - 20 (Mirena): This T shape & device has a collar attached to vertical arm containing 52 mg of levonorgestrel dispersed in poly dimethylsiloxane. It releases 15$\mu$g of levonorgestrel per day in vivo and is effective for 7-10 years.

Lippes loop: These devices are made of plastic or stainless steel only and do not release copper.

Copper -T (Cu-T): It is a T shaped device with a polyethylene frame holding a exposed surface area of copper. The IUD frame contains barium sulfate thus making it radio-opaque.
