Final answer:
The correct phase as part of the ovarian cycle is the follicular phase.
Step-by-step explanation:
The correct answer is B) Follicular phase. The follicular phase is part of the ovarian cycle and occurs before ovulation. During this phase, the ovarian follicles mature and prepare to release an egg. It is characterized by a rise in follicle-stimulating hormone (FSH) levels and the secretion of estrogen by the maturing follicle. The follicular phase typically lasts about 12 to 14 days in a 28-day menstrual cycle.
