Final Answer :
A
Explanation :
A score of 115 is one standard deviation above the mean of 100 on the Wechsler Adult Intelligence Scale. This puts Scott in the 84th percentile, which means that he scored higher than 84% of the population that took the test. The statement that intelligence tests are unreliable and have poor validity is not entirely accurate, as validity and reliability can vary depending on the specific test and how it is administered. However, it is important to consider the limitations and potential biases of any psychological assessment.
