Option c is right choice

Hi! The answer is option C. because 4.6 - 6.4 = -1.8 -1.8 - 12 = -13.8 and the expression we are looking for a match to is -13.8 as well so you know we’ve found the answer. The expression we are looking for a matching answer to is -6.4 - 12 = -18.4 + 4.6 = -13.8
It can’t be option A. because it equals -23 and that doesn’t much to the expression we are looking for answer. Option B. can’t be correct either because it equals -1 and that isn’t right either and lastly option D. can’t be right because it equals -10.2. I hope I explained it good enough, Goodluck :)
