B) 281.79 days
C) 261.36 days
D) 290.37 days

Answer 1

A full-term pregnancy lasts approximately 270 days from conception to birth. Durations below 240 days or above 306 days would be considered unusual. Of the given durations, only 290.37 days would be considered unusual.

Step-by-step explanation:

A full-term pregnancy lasts approximately 270 days (approximately 38.5 weeks) from conception to birth. Obstetricians set the due date as 284 days (approximately 40.5 weeks) from the last menstrual period (LMP). Any pregnancy duration below 240 days or above 306 days would be considered unusual.

To determine if the given durations are unusual, we compare them to the normal range.

1. A) 251.64 days: This duration is within the normal range.
2. B) 281.79 days: This duration is within the normal range.
3. C) 261.36 days: This duration is within the normal range.
4. D) 290.37 days: This duration is considered unusual as it is above the normal range.
