The cells of the payoff matrix show:

A. the profit that each producer can expect to earn from every combination of strategies by the firms in the market.
B. the profit that each producer can expect to earn by pursuing a single strategy.
C. the expected profits of rival firms.
D. the strategy that a firm must pursue to earn various levels of profit.
