The concept of mental age is used to compare the cognitive abilities of individuals of different ages. In this case, the child's mental age is 10 because they scored like an average 10-year-old on the intelligence test. To calculate their IQ, we use the formula: IQ = (mental age/chronological age) x 100. So, IQ = (10/8) x 100 = 125. Therefore, the correct answer is D - 10;125.
