Final Answer :
B
Explanation :
The formula for calculating IQ is (Mental Age / Chronological Age) * 100. Given Benjy's IQ is 120 and his chronological age is 5, we can rearrange the formula to find his mental age: Mental Age = (IQ * Chronological Age) / 100. Plugging in Benjy's values gives us (120 * 5) / 100 = 6. Therefore, Benjy's mental age is 6 years.
