    Yep. The answer is A. I have done this test.

    Here's what is wrong:
    B. Is completely wrong because remember there are NEGATIVE tiles too. And in this equation there are more NEGATIVE tiles than positive.
    C. Has the wrong product; It would be -20 NOT -8.
    D. Has the wrong product; It would be -8. When subtracting NEGATIVE numbers, the answer will be NEGATIVE. Unless the number that you subtracted had a bigger sum than the 1st number, then, the answer would be POSITIVE. But in this question, it's MOST definitely NEGATIVE.
