Answer:
A. C. and D.
Explanation:
Now I can not be 100% sure since I can not see the chart, but I can go off of logic. So let´s get started
First we can eliminate answer B. Answer B does not make ANY sense. Why would the number 3 make a difference.
Now answer A and D. These answers are basically the same. So if one is true, the other is as well. For D, if it were the same number, just negative and positive, the sum would be 0.
So this makes A and D true
Answer C is backed up by answer D as well. They can only be the same distance if one is positive and the other is negative
