A. Parturition: Parturition refers to childbirth, which is initiated by the foetal ejection reflex. A-III
B. Placenta: The placenta is an organ that develops during pregnancy and is responsible for secreting the hormone human chorionic gonadotropin (hCG). B-IV

D. Fimbriae: Finger-like projections at the end of the fallopian tubes that help collect the ovum (egg) after ovulation. D-II
AB is a part of an electrical circuit (see figure). The potential difference \(V_A - V_B\), at the instant when current \(i = 2\) A and is increasing at a rate of 1 amp/second is:
