C.0

D.a positive or negative number, depending on the numbers used

Answer 1

Option C) 0

Explanation:

we know that

The opposite of a number is equal to the same number but with a different sign

The sum of a number with its opposite number is always equal to zero

The opposite of the number is equal to -x

Adds the number and its opposite

x+(-x)=0

therefore

The sum of these two numbers is zero
