$$4,000,000$ per year, and variable costs $$0\mathrm{.}30$ per unit. At alternative B$,$ fixed costs would be $$3,600,000$ per year, with variable costs of $$0\mathrm{.}34$ per unit. If annual demand is expected to be $9$ million units, which plant offers the lowest total cost?

A$)$ Plant A$,$ because it is cheaper than Plant B for all volumes below $10,000,000$ units.

B$)$ Plant B$,$ because it is cheaper than Plant A for all volumes below $10,000,000$ units.

C$)$ Plant A$,$ because it is cheaper than Plant B for all volumes.

D$)$ Plant B$,$ because it has the lower variable cost per unit.

E$)$ Neither Plant A nor Plant B$,$ because the crossover point is at $9$ million units.
