The figure below shows a family of cost curves for a firm.The subscripts 1,2,and 3 for the SRATC curves refer to different plant sizes. FIGURE 8-3
-Refer to Figure 8-3.Should this profit-maximizing firm ever consider moving from point E (output level Q₃ on SRATC₂) to point F (output level Q₅ on SRATC₃) ?

A) No,because they are already producing at their lowest possible cost at point E.
B) Yes,because the firm can take advantage of economies of scale.
C) Yes,because SRATC₃ is the optimal plant size for this firm.
D) No,because producing at point F implies a higher cost per unit of output.
E) Yes,if the product price rises enough to lead the firm to expand to plant size 3.
