The correct answer is letter "C": changes as the related activity changes.
Explanation:
Cost behavior refers to the changes in total costs in front of changes due to certain events. Cost behavior is responsible for companies to classify costs in fixed costs -total costs do not vary even if there are changes in production, variable costs -total costs change when production changes, and mixed costs which is a combination of fixed and variables costs.
For a company, rent represents a fixed cost while raw materials represent a variable cost.
