Final Answer :
C
Explanation :
A deviation IQ score of 75 is below the mean for the general population (which is set at 100) and indicates that the cousin's score is within one standard deviation below the mean for individuals in their age group. It does not provide information about the percentage of questions answered correctly or the percentile rank. Additionally, the age group associated with the mean score of 100 for intelligence tests is typically the test-taker's age, not 9 years old.
