The correct option is D tubectomy, a minor surgery performed in females in which the fallopian tubes are tied and cut.
The image given in the question represents the human female reproductive system in which the fallopian tubes are tied and cut. It is a surgical method of contraception performed in females and is known as tubectomy or tubal ligation.
As the fallopian tubes are blocked after surgery, the egg released from the ovary is prevented from meeting the sperm. Thus tubectomy prevents conception.
Tubectomy does not interfere with the production of ova and also does not inhibit ovulation.
Vasectomy is a surgical method of contraception and involves tying and cutting of vas deferens in males. Thus vasectomy blocks the transport of sperms but does not stop the production of sperms.
