91. Table 1.1 shows the hypothetical trade-off between different combinations of Stealth bombers and B-1 bombers that might be produced in a year with the limited U.S. capacity, ceterisparibus. Complete the table by calculating the required opportunity costs for both the B-1 and Stealth bombers.
On the basis of your calculations in Table 1.1, you may infer that the law of increasing opportunity costs applies to
A. Stealth bombers but not to B-1 bombers.
B. B-1 bombers but not to Stealth bombers.
C. Both B-1 bombers and Stealth bombers.
D. Neither B-1 bombers nor Stealth bombers.
