Which combining form means pertaining to infants and children?

• A. Ped/o
• B. Bucc/o
• C. Axill/o
• D. Gnath/o

Answer: (A)

The main idea here is recognizing combining forms that indicate a patient population. ped/o means child, and it’s used in terms like pediatric, pediatrician, and pediatrics to refer to infants and children. That makes it the best fit for “pertaining to infants and children.”

The other roots point to body parts rather than age groups: bucc/o is cheek, axill/o is armpit, and gnath/o is jaw. So they don’t convey anything about age or patient type.
