Match List-I with List-II.List-IList-II(A) Nirodh(I) Used within 72 h…

The correct answer is Option (3) → A-II, B-III, C-I, D-IV

(A) Nirodh — this matches (II) A popular brand of condom for the male. A condom is a barrier method: the thin rubber/latex sheath stops the ejaculated semen from entering the female reproductive tract.

(B) Implants — this matches (III) Placed under the skin; effective period much longer than that of pills. Implants carry progestogens alone or with estrogen. They act like oral pills, which inhibit ovulation and implantation and alter the quality of cervical mucus, but one implant works for a much longer time.

(C) Progestogen-estrogen combination as an emergency contraceptive — this matches (I) Used within 72 hours of coitus to avoid possible pregnancy. An emergency contraceptive is taken after coitus, for example after rape or casual unprotected intercourse. IUDs placed within 72 hours work the same way.

(D) Tubectomy — this matches (IV) A small part of the fallopian tube is removed or tied up through a small incision in the abdomen or through vagina. Tubectomy is sterilisation of the female, a terminal method. It blocks the transport of gametes, so conception cannot take place, and the operation can rarely be reversed. Its male counterpart is vasectomy, in which the vas deferens is cut or tied.

NCERT Extract:
Population Stabilisation and Birth Control – “… ‘Nirodh’ is a popular brand of condom for the male. Use of condoms has increased in recent years due to its additional benefit of protecting the user from contracting STIs and AIDS.”
Population Stabilisation and Birth Control – “Progestogens alone or in combination with estrogen can also be used by females as injections or implants under the skin (Figure 3.3). Their mode of action is similar to that of pills and their effective periods are much longer. Administration of progestogens or progestogen-estrogen combinations or IUDs within 72 hours of coitus have been found to be very effective as emergency contraceptives as they could be used to avoid possible pregnancy due to rape or casual unprotected intercourse.”
Population Stabilisation and Birth Control – “… Sterilisation procedure in the male is called ‘vasectomy’ and that in the female, ‘tubectomy’. In vasectomy, a small part of the vas deferens is removed or tied up through a small incision on the scrotum (Figure 3.4a) whereas in tubectomy, a small part of the fallopian tube is removed (Figure 3.4b) or tied up through a small incision in the abdomen or through vagina.”
