| Column I | Column II |
| A. Saheli | i. reusable |
| B. Vaults | ii. once in a week |
| C. Pills | iii. hormone-releasing IUD |
| D. Progestasert | iv. inhibit ovulation and implantation |
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → A - ii, B - i, C - iv, D - iii.
(A) Saheli — this matches (ii) once in a week. Saheli is an oral contraceptive pill for women. It has a non-steroidal preparation and is taken only once a week, with very few side effects.
(B) Vaults — this matches (i) reusable. Vaults, diaphragms and cervical caps are rubber barriers placed over the cervix during coitus. They block the entry of sperms and can be used again.
(C) Pills — this matches (iv) inhibit ovulation and implantation. Pills contain progestogens or progestogen-estrogen combinations and are taken daily for 21 days. They stop ovulation and implantation and also change the cervical mucus so that sperms cannot enter.
(D) Progestasert — this matches (iii) hormone-releasing IUD. An IUD (intra uterine device) is placed in the uterus by a doctor or nurse. Progestasert and LNG-20 release hormones, which make the uterus unsuitable for implantation.
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. … 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) …. … Oral administration of small doses of either progestogens or progestogen–estrogen combinations is another contraceptive method used by the females. They are used in the form of tablets and hence are popularly called the pills. … They inhibit ovulation and implantation as well as alter the quality of cervical mucus to prevent/retard entry of sperms. … Saheli–the new oral contraceptive for the females contains a non-steroidal preparation. It is a ‘once a week’ pill with very few side effects and high contraceptive value.”
