Explanation:
The subject of this question is related to IQ scoring system used in the field of psychology, specifically the Stanford-Binet intelligence scale. IQ (or Intelligence Quotient) is determined by a comparison of a child's mental age and chronological age. In the case of five-year-old Benjy, his mental age is determined by the equation: IQ = (Mental Age/Chronological Age) * 100. Given that Benjy's IQ is 120, we can use that equation to find his mental age: Mental Age = (IQ * Chronological Age) / 100 . Thus, in this case, Benjy's mental age would compute to: (120 * 5)/100 = 6. So, option B) 6, is the correct answer.
