Capital (K) Q= 100 Labor (L) The firm's optimization problem is to minimize total cost for a given level of output. In the diagram above, why is that achieved at point E rather than at point F? Select one: O a. Although E uses more labor than F, output is higher to compensate for increased costs. O b. Total costs are the same at Fand E, but the firm prefers the combination of inputs at E. O c. F uses more capital than E, and capital tends to be more expensive than labor. O d. Total costs at E are lower than at F because E is on a lower isocost line.
