<p>C. The only way there's a remainder of 3 is if 12 is a multiple of k and k is greater than 3. So it could be 4, 6, or 12.</p>

<p>You could also just do the remainder for 15 divided by every integer up to 15.</p>

<p>idk if my explanation is that great, tell me if you need it explained better.</p>
