A) \[C\to A\to D\to B\to E\]
B) \[A\to C\to E\to D\to B\]
C) \[A\to D\to C\to E\to B\]
D) \[B\to A\to C\to D\to E\]
Correct Answer: B
Solution :
In human female reproductive cycle or menstrual cycle during proliferative phase, the anterior lobe of pituitary gland secretes the Follicle Stimulating Hormone (FSH), which stimulates to ovarian follicles to secrete estrogens. During the second week of reproductive cycle, most of the developing follicle die and usually one follicle continues to mature. Now the Luteinizing Hormone (LH) in blood level increases by pituitary gland. A small surge of FSH also occurs. Now ovulation takes place, which releases immature egg into abdominal cavity. During ovulation, the follicle breaks open and collapses under the continuous influence of Luteinizing Hormone (LH). It begins to enlarge and forms a yellowish structure, called corpus luteum or yellow body.
