(a) Both A and R are true and R is the correct explanation of this.
Explanation:
Surgical methods of contraception (sterilization) prevent pregnancy by blocking the transport of gametes and thus their fertilization. The surgical method in men is called vasectomy, and in women, it is called tubectomy. Both methods are very effective, but their reversibility is very low. Surgical sterilization in men (vasectomy), on the other hand, is so simple that it can be performed under local anaesthesia in 10 minutes and is often referred to as a "low table" operation. Tubectomy is a method of contraception and permanent sterilization in women. It is a major operation in which the fallopian tubes are blocked or cut to prevent the egg from reaching the uterus from the ovaries, eliminating all possibilities of pregnancy.
