a, b, c, and d are positive integers where a is divisible by b and c is divisible by d. Which of the following is NOT necessarily an integer?\nOptions:\n(A) (ac) /(bd) \n(B) a/b + c/d\n(C) (a + c) /(b + d) \n(D) (abc) /d\n(E) (acd) /b Now, let's think a bit. Some random thoughts:

As per the question, let a = 10, b = 5, c = 6, and d = 2. Plugging these into the answer choices, only C does not yield an integer.
The final answer: (C).
