The average period of giving birth to a full-term baby is –

Correct option is B

Sol. The normal gestational period from the last menstrual period is approximately 280 days or 40 weeks. This is considered the typical duration of a full-term pregnancy, where the fetus undergoes all stages of development, resulting in a healthy birth.
Explanation of each option:
· (a) 250 days – Incorrect. A gestational period of 250 days is shorter than the average 280 days, which may indicate a preterm birth. This duration would typically not allow for complete fetal development, leading to a premature birth.
· (b) 280 days – Correct. This is the standard full-term pregnancy duration, with a 40-week gestation period from the last menstrual period. It is the typical duration where fetal development is considered optimal.
· (c) 200 days – Incorrect. A gestation period of 200 days is extremely preterm, and it would not result in a viable pregnancy. Fetal development would be underdeveloped, leading to a significantly increased risk of complications.
· (d) 150 days – Incorrect. A gestation period of 150 days is far too short and indicates severe prematurity. At this stage, the fetus would be very underdeveloped and unlikely to survive without significant medical intervention.
