Study the given statement and answer the question. "During 'P' phase of the menstrual cycle, if pregnancy doesn't happen, the 'Q' withers and dies, usually around day 22 in a 28 -day cycle. The drop in 'R' levels causes the lining of the uterus to fall away. This is known as 'S'. Identify $\mathrm{P}, \mathrm{Q}, \mathrm{R}$ and S.
  1. A $\mathrm{P} \rightarrow$ menstrual, $\mathrm{Q} \rightarrow$ graafian follicle, $\mathrm{R} \rightarrow$ estrogen, $\mathrm{S} \rightarrow$ menarche
  2. B $\mathrm{P} \rightarrow$ luteal, $\mathrm{Q} \rightarrow$ corpus luteum, $\mathrm{R} \rightarrow$ progesterone, $\mathrm{S} \rightarrow$ menstruation
  3. C P → ovulatory, $\mathrm{Q} \rightarrow$ endometrium, $\mathrm{R} \rightarrow$ follicle stimulating hormone, $\mathrm{S} \rightarrow$ menopause
  4. D $\mathrm{P} \rightarrow$ follicular, $\mathrm{Q} \rightarrow$ secondary oocyte, $\mathrm{R} \rightarrow$ luteinizing hormone, $\mathrm{S} \rightarrow$ menstruation
