B) the average variable cost is decreasing and the average total cost is increasing.
C) both the average variable and average total cost are decreasing.
D) the average variable cost is decreasing and the average total cost may be increasing or decreasing.
E) the average variable cost may be rising or falling, but the average total cost is declining.
