B Correct answer
Explanation

This is an algebraic identity. Let the original number be n. Double it: 2n. Add 10: 2n + 10. Divide by 2: n + 5. Subtract original number n: 5. The result is always 5 regardless of the starting number. This works because the operations are designed to cancel out the original number.
