Which of the following represents a tolerance of ±5%?

Explanation:
Tolerance defines how much a value may vary from its nominal value. A tolerance of ±5% means the value can be 5% above or 5% below the nominal value. For example, if the nominal value is 100 units, the acceptable range is 95 to 105 units. The other options represent smaller or larger deviations: ±1% gives 99–101, ±2% gives 98–102, and ±10% gives 90–110. Since only the ±5% range matches the stated tolerance, that is the correct choice.
