Explanation: As discussed in the text; primordial follicle has granulosa cells and theca cells.
In the Dominant follicle, there is marked enlargement of granulosa cells with lipid inclusion under the influence of FSH and estrogen. (i.e. option d is correct)
Granulosa cells produce estrogen and inhibin B in the first half of the menstrual cycle. (So option b is incorrect). The granulosa cells do not have a blood supply. The granulosa cells layer become vascularised only after ovulation with the formation of corpus luteum.
