Final answer:
Babies that are considered appropriate for gestational age are within the 10th to 90th percentile range for birth weight.
Step-by-step explanation:
Babies that are classified as appropriate for gestational age fall within a specific percentile range for their weight at birth. This range typically reflects babies who have grown at a rate that is expected for the length of time they have spent in utero. The correct percentile range for babies that are considered appropriate for gestational age is from the 10th to the 90th percentile. Babies below the 10th percentile are often classified as small for gestational age (SGA), while those above the 90th percentile are frequently considered large for gestational age (LGA).
The answer to the question is b. 10th-90th percentile. This range indicates that a baby has grown at a rate that is typical among peers when accounting for the duration of the pregnancy, thereby standing between the smallest 10% and the largest 10% of babies of the same gestational age.
