- ✓Estrous phase
- CEarly stage of meta$-$estrus phase
- DDiestrus phase
✓
Answer
Correct option: B.
Estrous phase
Estrous cycle, or oestrous cycle, is the reproductive cycle found in most mammalian placental females, whereby there are recurring periods when the female is fertile and sexually receptive $($estrus$)$ interrupted by periods in which the female is not fertile and not sexually receptive $($anestrus$).$
Animals that have estrous cycles reabsorb the endometrium $($inner membrane of the mammalian uterus$)$ if conception does not occur during that cycle.
During the estrous period also known as heat period, mature eggs are released from the ovaries.
