Answer 1

Hint: Humans use contraception to prevent conception even after sexual activity. By stopping the release of eggs or stopping fertilisation, contraception can prevent pregnancy. The use of contraceptive techniques is encouraged for a variety of reasons.

Complete Step by Step Answer:
Oral contraceptives and birth control pills are intended for female consumption in order to prevent pregnancy. It modifies the cycle to stop ovulation and prevent conception. By preventing the release of the hormones FSH and LH, which are essential for ovulation, oral contraceptives prevent ovulation. They are hormonal preparations that either contain oestrogen and progestin in combination or progestin by itself, which prevents the ovaries from releasing eggs. The main hormone responsible for preventing pregnancy is progesterone. The best mode of action is ovulation prevention; they impede follicular growth and delay ovulation.
Mechanical barriers are objects that provide a physical barrier between the sperm and the egg. Mechanical barriers include things like the diaphragm, cervical cap, spermicide, male and female condoms, and the condom. The condom is the only method of birth control that has been proven to prevent STIs.
A vasectomy is a surgical procedure used to sterilise males or provide long-term birth control. To stop sperm from entering the urethra, the vas deferens is sliced, separated, and knotted during the process. This stops a female egg from being fertilised during sexual activity.
CuT, Cu7, and Multiload 375 copper IUDs increase sperm phagocytosis in the uterus and the Cu ions that are produced reduce sperm motility and sperm fertility. It renders the cervix hostile to the sperms and the uterus unfit for implantation. It is the main method of birth control for ladies who want to avoid getting pregnant or spacing out their children.
Hence, the correct option is A. A-III; B-I; C-IV; D-II

Note: Contraceptives also have their merits and demerits, so one should choose the contraceptive according to their own need and considering the different mode of action of different contraceptives.
