Answer: C) Isaiah is a person with savant syndrome.
Step-by-step explanation:
Savant syndrome refers to a condition in which a person with important mental disabilities shows special skills in which they excel, mostly associated with a massive memory.
An IQ under 70, such as the 65 that Isaiah has, makes him a person with an intellectual disability. However, his peculiar skill shows that he might have Savant syndrome.
Around 10% of people with autistic disorder have Savant syndrome at different levels, although it also appears in people with other developmental disabilities.
