Answer:
C) the market price falls below $170 per unit.
Explanation:
If this firm is a price taker, it means that it is operating in a perfect competition market. In such markets, since the entry and exit barriers are very low or nonexistent, if the equilibrium price falls below the variable cost, the firms should halt production in the short run until the equilibrium price rises again. The firm should resume production only after the equilibrium price exceeds the variable costs.
This situation is only applicable on the short run. On the long run the firm should only produce if the equilibrium price is greater or equal to its marginal cost.
