Correct Answer » B

The Developmental Quotient (DQ) is calculated by comparing a child’s Developmental Age (DA) to their Chronological Age (CA) using the formula:
DQ = (Developmental Age / Chronological Age) × 100
Chronological Age (CA): The boy is 6 years old.
Developmental Age (DA): The question states the boy has recently started telling his full name but cannot yet recite a poem.
Telling a full name is a milestone typically achieved at 3 years of age.
Reciting a poem is a more advanced milestone usually achieved by 5 years of age.
Since he has mastered the 3-year milestone but not the 5-year one, his developmental age in the language sphere is assessed at 3 years.
Calculation:
DQ = (3 / 6) × 100 = 50%
