The correct answer is Option (3) → Copper loaded Intra Uterine Device - LNG-20

Intra Uterine Devices (IUDs) are placed in the uterus through the vagina by a doctor or an expert nurse. They are of three kinds: non-medicated IUDs, copper-releasing IUDs and hormone-releasing IUDs.

(1) Hormone releasing Intra Uterine Device - Progestasert — Correct match. Progestasert and LNG-20 release a hormone.

(2) Non-medicated Intra Uterine Device - Lippes loop — Correct match. The Lippes loop is a plain device with no copper and no hormone.

(3) Copper loaded Intra Uterine Device - LNG-20 — Incorrect match. LNG-20 is a hormone-releasing device. The copper-releasing devices are CuT, Cu7 and Multiload 375.

(4) Contraceptive barriers made of rubber - Vaults — Correct match. Diaphragms, cervical caps and vaults are rubber barriers placed over the cervix. They stop sperms from entering the uterus and can be used again.

NCERT Extract:
Population Stabilisation and Birth Control – “… Diaphragms, cervical caps and vaults are also barriers made of rubber that are inserted into the female reproductive tract to cover the cervix during coitus. They prevent conception by blocking the entry of sperms through the cervix. They are reusable. Spermicidal creams, jellies and foams are usually used alongwith these barriers to increase their contraceptive efficiency. Another effective and popular method is the use of Intra Uterine Devices (IUDs). These devices are inserted by doctors or expert nurses in the uterus through vagina. These Intra Uterine Devices are presently available as the non-medicated IUDs (e.g., Lippes loop), copper releasing IUDs (CuT, Cu7, Multiload 375) and the hormone releasing IUDs (Progestasert, LNG-20) (Figure 3.2).”
