V. Teenager
Codes :
UGC NET - 2013,
Answer: B
By chronological age the stages are infant (III), toddler (I), early adolescence (II), teenager (V) and youth (IV). So the code is III, I, II, V, IV.
An infant is up to about one or two years old, a toddler is from about one to three years, early adolescence follows childhood and precedes the teenage years, and youth comes after the teens. The other codes put youth or toddler out of place.
The terms are based on age ranges: infancy covers the first year or two, toddlerhood the second and third year, early adolescence about 10 to 13, the teens up to 19, and youth the years after. Arranging the five in this order gives the key.
