Vedclass · Answer

(B) In the menstrual cycle,the hormonal levels change as follows:$1$. $A$ represents $FSH$ (Follicle Stimulating Hormone),which shows a gradual increase during the follicular phase.$2$. $B$ represents Estrogen,which rises steadily during the follicular phase as the follicles develop.$3$. $C$ represents $LH$ (Luteinizing Hormone),which shows a sharp peak ($LH$ surge) around day $14$,triggering ovulation.$4$. $D$ represents Progesterone,which is secreted by the corpus luteum and rises significantly during the luteal phase (after day $14$) to maintain the endometrium.Therefore,the correct identification is $A ightarrow 	ext{FSH}, B ightarrow 	ext{Estrogen}, C ightarrow 	ext{LH}, D ightarrow 	ext{Progesterone}$.
