Final answer:
The ideal standard can only be achieved under perfect conditions and is theoretical, serving as a goal for continuous improvement. Option c is correct.
Step-by-step explanation:
The type of standard that can be achieved only under perfect conditions is the ideal standard. Ideal standards are theoretical benchmarks that assume everything operates under the best possible scenario without any interruptions, breakdowns, or variances in performance.
These standards serve as a goal for continuous improvement but are not expected to be met regularly in practice since they do not account for the normal working conditions that include delays, machine wear and tear, and human error.
Achievable standards, on the other hand, take into account these realities and set goals that are realistic and attainable while still posing a challenge, and they can serve as a more practical form of motivation and performance assessment.
Hence, option c is correct.
