Explanation

The typical number of bones in a newborn infant is around 270 to 300, but many sources cite closer to 280 or fewer initially. Option C (280) is often cited as the approximate count for newborns due to cartilage and unfused joints. Option A (206) is the number of bones in an adult skeleton. Option B (230) does not match common anatomical counts for infants. Option D (300) is too high compared to standard ranges.
