Answer:
c. 8
Step-by-step explanation:
A composite number is a number that can be divided evenly by more numbers than 1 and itself. The number 8 can be evenly divided by 1, 2, 4 and 8, with no remainder. Since 8 cannot be divided by just 1 and 8, it is a composite number.
While 3, 5, and 11 are Prime numbers since it can only be divided by 1 and itself.
