The Payoff Matrix Below Shows the Payoffs to Firms a and B

The payoff matrix below shows the payoffs to Firms A and B from producing different levels of output. The numbers in parentheses are (payoff to A, payoff to B) . $$\begin{array} { l l | c | c } & & { \text { Firm B } } \\& & \text { Produce } & \text { Produce } \\& & 1000 \text { Units } & 2000 \text { Units } \\\hline & \text { Produce } & & \\& \text { 1000 Units } & ( 100,100 ) & ( 10,150 ) \\\text { Firm A } & & & \\& \text { Produce } & (150,10) & ( 30,30 ) \end{array}$$ TABLE 11- 3
-Refer to Table 11- 3. From the payoff matrix we can infer that

A) there is no Nash equilibrium in the game.
B) it is optimal for Firm A to produce 1000 units of output regardless of what Firm B is doing.
C) it is optimal for Firm B to produce 1000 units of output regardless of what Firm A is doing.
D) both firms are indifferent between an equilibrium (Produce 1000 units, Produce 1000 units) and (Produce 2000 units, Produce 2000 units) .
E) it is optimal for Firm A to produce 2000 units of output regardless of what Firm B is doing.
