Quizplus · Accepted Answer

According to the intelligence quotient formula, IQ = (mental age/chronological age) x 100. If an individual has a chronological age greater than their mental age, then the mental age/chronological age fraction will be less than 1. Multiplying this by 100 will result in an IQ score that is less than 100, indicating below average intelligence. Therefore, the correct choice is D.
