Solution

The correct option is C A–(c), B–(a), C–(d), D–(b)
The contraceptive pills contain the hormones which prevent the process of ovulation.

The condom is a physical barrier which prevents the sperms from reaching the cervix.

The process of vasectomy leads to the cutting, sealing or ligating of the vas deferens in males. This causes the release of the semen without the sperms.

Copper T is an intrauterine device which releases copper ions within the uterus and supress sperm motility, prevents fertilisation and implantation.
