The term infant is used for a child of age:

Correct option is B

Ans. (b)
Sol. An infant is a child aged from birth to 1 year. This stage includes neonates (0-28 days old) and post-neonatal infants (1 month to 1 year). Infants undergo rapid growth and development, including motor skills, sensory development, and immune system maturation.
Explanation of each option:
· (a) 0 - 2 months – Incorrect. This only includes neonates and early infancy but does not cover the full infant period.
· (b) 2 months - 1 year – Correct. The term infant covers from birth up to 1 year, including both neonates and older infants.
· (c) 1 - 4 years – Incorrect. A child aged 1-4 years is classified as a toddler rather than an infant.
· (d) 1 - 10 years – Incorrect. This range includes toddlers, preschoolers, and school-age children, not infants.
Thus, the correct answer is (b) 2 months - 1 year, as infants are children under the age of one year.
