Intelligence Quotient (I.Q.) in mild mental retardation is-

Appeared in: RUHS, Jaipur, PB B.Sc Nursing Entrance-2022

Explanation

The IQ range of 50–70 is the standard classification for mild intellectual disability.
This is the most common level, accounting for approximately 85% of all individuals with an intellectual disability.
Individuals in this range are often considered 'educable' and can develop social and communication skills.
With appropriate support, they can live semi-independently and hold jobs.

Why Other Options Were Wrong

Option A: An IQ score below 50 encompasses the categories of moderate, severe, and profound intellectual disability, not mild.
Option C: An IQ range of 70–80 is classified as 'borderline intellectual functioning,' which is not considered an intellectual disability. The cutoff for intellectual disability is an IQ of approximately 70 or below.
Option D: An IQ range of 80–90 falls into the 'low average' intelligence category, which is within the normal range of human intelligence.
