Question

Match the IUDs in Column I with suitable example in Column II.

Column I	Column II
a. Non-medicated	i. Lippes loop
b. Copper releasing	ii. LNG-20
c. Hormone releasing	iii. Multiload 375

• A. a-iii, b-ii, c-i
• B. a-i, b-ii, c-iii
• C. a-i, b-iii, c-ii
• D. a-ii, b-i, c-iii

Hint:

Lippes loop is non-medicated, Multiload 375 releases copper, LNG-20 releases a hormone.

Answer 1

The Correct Option is C

Step 1: Understand the concept:
Intra-uterine devices (IUDs) are placed in the uterus to prevent pregnancy. NCERT groups them into three types: non-medicated, copper releasing and hormone releasing.

Step 2: Match each type with its example:
a. Non-medicated IUDs have no drug. The example is the Lippes loop, so a matches i.
b. Copper releasing IUDs release copper ions, which lower sperm motility and fertilising ability. Examples are CuT, Cu7 and Multiload 375, so b matches iii.
c. Hormone releasing IUDs release a progestogen. LNG-20 releases levonorgestrel, so c matches ii.

Step 3: Check the options:
Option (A) gives a-iii, which wrongly calls Multiload 375 non-medicated. It is wrong.
Option (B) gives b-ii, which wrongly calls LNG-20 copper releasing. It is wrong.
Option (D) gives a-ii, which wrongly calls the hormone releasing LNG-20 non-medicated. It is wrong.
Option (C) gives a-i, b-iii, c-ii and is correct.

Final Answer:
The correct matching is a-i, b-iii, c-ii, which is option (C).
