Correct Answer is A
Explanation
A. 21 lbs
This is the correct answer. Infants typically triple their birth weight by 1 year. A baby who weighed 7 lbs at birth would generally weigh around 21 lbs at 1 year.
B. 28 lbs
This weight is too high for a typical 1-year-old. It is more in line with the weight of a 2-year-old. At 1 year, most babies will weigh around 21 lbs, so 28 lbs would be above the typical weight range.
C. 14 lbs
This weight is too low for a 1-year-old. By 1 year, most babies will have tripled their birth weight, which in this case would be 21 lbs. A weight of 14 lbs would be considered below average for a 1-year-old.
D. 32 lbs
This weight is too high for a 1-year-old. While some babies may gain weight faster than others, a 1-year-old who weighed 7 lbs at birth would typically not weigh 32 lbs. This would be unusually heavy for a 1-year-old.
