Is this right? Thanks.

Determine whether the following statement is true or false. If the statement is false, make n(A U B) = n(A) + n(B) Choose the correct answer below. O A. The statement is false, n(A U B) = n(A n B). O B. The statement is false, n(A U B) = n(A) + n(B) + n(An B). O C. The statement is false: n(A U B) = n(A) + n(B) - n(An B) O D. The statement is true
