Answer:
B. fixed cost per unit increases
Explanation:
As we know that
If the production volume increases, the fixed cost per unit is decreases as it reflect an inverse relationship between the fixed cost per unit and the production volume
Let us take an example
Fixed cost = $20,000
Production volume = 100,000
Decrease in production volume = 80,000
So, the fixed cost per unit in the first case is
= 20,000 ÷ $100,000
= $0.2
And, the fixed cost per unit in the second case is
= 20,000 ÷ $80,000
= $0.25
Therefore, the fixed cost per unit increases
