Correct Answer - D
Unprotected intercourse without regard to the time of the month carries an 8% incidence of
pregnancy, an incidence that can be reduced to 2% by the use of emergency contraceptives within 72 hours of unprotected intercourse. 0.75 mg levonorgestrel are now approved for postcoital contraception and are available over the counter for women aged >17 years. Levonorgestrel is more effective and is associated with fewer side effects than the combination estrogen-progestin regimens Basically the methods used interfere with the physiological events before implantation, for e.g. inhibition or delaying of ovulation or interference with postovulatory events necessary for implantation & longevity of the blastocyst.

Submentovertical diameter is the longest diameter of fetal skull.
The submentovertical diameter extends from the junction of the floor of the mouth and neck to the highest point on sagittal suture.
Shortest diameters of fetal skull: Bimastoid (7.5 cm) > Bitemporal (8 cm)
Longest diameter
vertical (14 cm) > Supmentovertical

Correct Answer - A
Ans. A. 21 alpha-hydroxylase
The condition described above represents the Congenital adrenal
hyperplasia.
"More than 90% of CAH cases are caused by 21-hydroxylase
deficiency"
Congenital adrenal hyperplasia:
It is due to an inborn error of adrenal steroid metabolism, commonly
due to 21-hydroxylase (95%) and rarely due to 11-hydroxylase or 3Ξ²
hydroxysteroid dehydrogenase deficiency.
Clinical presentation
An ambiguity of sex at birth
Hirsutism and amenorrhea may be the presenting features around
puberty in a milder form.
The karyotype is 46, XX.
