Explanation / Answer

B. Increasing at decreasing rate.

Total cost is sum of fixed and variable cost. It is increasing at a constant rate of $15 per unit of output. But output is increasing at a diminishing rate. Initially with $15 increase in variable cost, outout increases by 80 units but later output increases by 40 units , 20 units.
