The correct statement about a number and its additive inverse is: Â C. Their sum is always zero.
Explanation:
1. The additive inverse of a number is the number that, when added to the original number, gives a sum of zero.
2. For example, the additive inverse of 5 is -5 because 5 + (-5) = 0. 3. Similarly, the additive inverse of -3 is 3 because -3 + 3 = 0. 4.
Therefore, the sum of a number and its additive inverse is always zero, making statement C the true statement.
