Answer to Question 1

C

Answer to Question 2

Firm B's reaction function is qB = 5 - (1/2)qA. The Stackelberg leader quantity is 5 and firm B will produce 2.5. Firm A's profit is 12.5. If firm A produces 6 units for example, firm B's best response is 2 units; however, it would incur a loss and not enter. Firm A's profits by preventing entry would be 24. Thus, firm A can deter entry by overproducing.
