Answer:

(A)30

(D)15

Step-by-step explanation:

Factors of 30 are 1,2,3,5,6,10,15 and 30

A composite number is any number that is not prime.

From the given options, the factors of 30 are 30, 5 and 15.

However, 5 is not a composite number.

Therefore, the number that Lacey could be thinking of will either be 30 or 15.
