Answer:
B. 29 is prime, not composite
Step-by-step explanation:
A composite number, by definition, is any positive integer of which can be formed by the product of two or more numbers, and the integer must not be a prime number.
29 is a prime and not a composite number because it is only divisible by 1 and itself.
This is not same for 39 and 49.
39 can be divisible by 3, and 13, other than 1 and 39.
49 can be divisible by 7, other than 1 and itself.
Therefore, Camila made a mistake by shading 29 as a composite number.
The answer is: "B. 29 is prime, not composite".
