The correct option is B

A-(iii), B-(i), C-(iv), D-(ii)


Pills: Check ovulation in females by inhibiting the secretion of follicle-stimulating hormone (FSH) and luteinising hormone (LH) which are necessary for ovulation.

Condom: It checks pregnancy by preventing deposition of the semen in the vagina.

Vasectomy: Although sperms are produced, they are reabsorbed into the body.

Copper T: Increases phagocytosis of spermatozoa within the uterus and the Cu ions released suppress motility of sperms as well as their fertilising capacity.
