Which of the following costs do not change in total despite changes in volume within the relevant range? A. mixed costs B. variable costs C. fixed costs D. total production costs

correct option is C. fixed costs

when the cost does not change in the total despite the change in volume that is in nature of fixed costs because in fixed cost it does not change in total but it only varies in the relation to the change in output quantity.

but in case of variable cost per unit is constant and changes in total.

so that correct option is C. fixed costs
