Answer 1

The correct option is C a-iii, b-i, c- iv, d- ii


Prevents ovulation :
Pills work by delaying ovulation (releasing of secondary oocytes from the ovary) or if ovulation has already occurred, they work to prevent fertilisation.

Condom- Prevents sperm reaching cervix :
Condom is a barrier method of contraception which prevents the physical meeting of sperm and ovum. These are used by both males and females. They are made up of latex or rubber sheets which cover the penis in males and cervix in females.

Vasectomy- Semen contains no sperm :
Vasectomy is a surgical contraceptive method performed in males.
In this method, a small part of vas deferens is cut and removed.
The remaining ends of the vas deferens are then ligated.
This disrupts the route of passage of sperm.

Copper-T- Prevents implantation :
Copper-T or Cu-T is a copper releasing IUD. It is a “T”-shaped device made up of plastic and copper wires.
It releases copper ions in the uterus where they suppress the motility of sperms. This ensures that the sperms do not reach the fallopian tube for fertilisation.
It is an ideal contraceptive used by the females for delaying pregnancy and having space between children.
