The relevant range refers to the range of activity within which the assumptions about fixed and variable costs are valid. It is indeed the normal range of output (A), the range where cost relationships (such as fixed and variable cost behaviors) are valid (B), and it can change over time due to various factors such as changes in production capacity or market conditions (C). Therefore, all of these statements are correct.
