Answer:
B. Puerperium, or fourth trimester of pregnancy 
Explanation:
- Puerperium or the fourth trimester of pregnancy is also known as the postpartum period. 
- This period starts immediately after the mother gives birth to a child. 
- During this period the size of the uterus and other reproductive organs along with the hormone levels return to their normal state.
- It is the phase where regression of all the anatomical and physiological changes that took place i in the reproductive organs of the females takes place.
- This phase is divided int three periods - 
1. Immediate puerperium, or the first 24 hours after parturition
2. Early puerperium, which extends until the first week postpartum; 
3. Remote puerperium, which includes the period required for involution of the genital organs and return of menses, usually approximately 6 weeks.
- This phase is highly critical for the mother as this requires rest and proper care as there are risks of bleeding. Therefore, the midwife or the nurse must take proper care of the mother.
