Answer: C. Ideal Standard

Explanation: The correct answer is “Ideal Standard” because this type of standard represents a theoretical level of performance achievable only under perfect conditions, with no allowance for inefficiencies like wastage, idle time, or machine breakdown.

Run down: The answer “Ideal Standard” was selected because it is used in cost accounting to define the best possible performance scenario. It is often unattainable in real life but is useful for setting benchmarks or performance goals. These standards provide an ideal target but are rarely achieved due to everyday operational inefficiencies.
