Solution

The correct option is A DMAU
Male pills are formulated by using the chemical Dimethandrolone undecanoate (DMAU) which inhibits the pituitary gland from producing both follicle-stimulating hormones (FSH) and luteinising hormones (LH). FSH and LH control the process of spermatogenesis.

Intrauterine devices (IUDs) are the devices that are inserted inside the uterus. It prevents pregnancy by stopping the sperms from reaching the ovum. LNG- 20 is an intrauterine hormone-releasing IUD. Levonorgestrel, a synthetic progesterone is released 20 micrograms per day. It causes thinning of the uterine lining (endometrial atrophy) and inhibits implantation along with the sperm phagocytosis​.

Saheli is an oral non-steroidal preparation that works by inhibiting implantation. It contains Centchroman (Ormeloxifene), a selective estrogen receptor modulator.
The vaginal ring is a hormone based soft plastic ring that contains two hormones – oestrogen and progestogen. It is worn by the famale in her vagina. It works similar to hormonal pills, by releasing a conitnuous dose of estrogen and progesterone.
