The Stanford-Binet IQ is calculated by dividing the mental age by the chronological age and then multiplying it by 100. Therefore, to convince Professor Terman that he is smarter than he actually is, Bill needs to show a higher mental age than his actual chronological age. Dividing a younger age by his actual chronological age will result in a higher IQ score, which is what Bill needs to achieve a score of 115. So, the correct choice is C.
