Answer:
Answer choice D.
Explanation:
We can see that 7.8 is in absolute value. This just turns the number positive, it doesn't change it's value other than turning it a positive number. So that means that it can't be A or B because those two are negative. And it can't be C since it just doesn't make sense, and I wouldn't understand how they got 0. Therefore, it is D. I hope this helps, and I hope it's not wrong, but I don't think it is.
