Table 12 Shows the Hypothetical Trade-Off Between Different Combinations of Stealth

Table 1.2 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, ceteris paribus.Complete the table by calculating the required opportunity costs for both the B-1 and Stealth bombers.
$\begin{array}{|c|c|c|c|c|}\hline & \begin{array}{c}\text { Number of } \\\text { Stealth } \\\text { Bombers }\end{array} & \begin{array}{c}\text { Opportunity Cost of } \\\text { Stealth Bombers in } \\\text { Terms of B-1 } \\\text { Bombers }\end{array} & \begin{array}{c}\text { Number of } \\\text { B-1 } \\\text { Bombers }\end{array} & \begin{array}{c}\text { Opportunity Cost of B- } \\\text { 1 Bombers in Terms of } \\\text { Stealth Bombers }\end{array} \\\hline \text { A } & 195 & & 20 & \\\hline \text { B } & 180 & & 35 & \\\hline \text { C } & 150 & & 45 & \\\hline \text { D } & 100 & & 50 & \\\hline\end{array}$
Table 1.2
Production Possibilities for Bombers Refer to Table 1.2.In the production range of 20 to 35 B-1 bombers, the opportunity cost of producing 1 more B-1 bomber is

A) 195/20 of Stealth bombers.
B) 35/20 of Stealth bombers.
C) 15 Stealth bombers.
D) 1 Stealth bomber.
