The relevant range in cost accounting refers specifically to the range of activity over which the assumptions of fixed and variable costs hold true. Within this range, total fixed costs remain constant, regardless of the activity level, while unit variable costs do not change as production volumes fluctuate.

Understanding this concept is crucial for accurate cost analysis and decision-making. Outside the relevant range, fixed costs may change due to factors like capacity constraints, and variable costs may escalate or decrease as additional resources are required or become more efficient. Recognizing the relevant range allows businesses to predict costs and assess profitability accurately within expected operating levels, providing a realistic framework for budgeting and performance evaluation.

The other options center around concepts that do not accurately define the relevant range. For example, the variation of total fixed costs is not applicable within the relevant range, as fixed costs should remain constant there. Additionally, while total production capacity is an important metric, it does not specifically indicate the conditions of cost assumptions, nor does the idea that companies compete solely on price pertain to the definition of the relevant range.
