AThe number one
BThe number zero
CEvery whole number
DNo number at all
Answer & Solution
Correct answer: B. The number zero
1. The opposite of a number sits the same distance from zero, on the other side.
2. Zero sits at no distance from zero at all.
3. So there is no other side for it to move to, and zero is its own opposite.
4. Every other number has a distinct partner on the far side of zero.
