I would like to know whether I have chosen the right about these Game Theory questiones.

Which one ofthe following statements is incorrect? O A. A nite static game with complete information may not have a pure strategy Nash equilibrium. Q) B. For dynamic games with complete information, not all subgame perfect Nash equilibrium points can be found by backward induction. 0 C. A finite dynamic game with complete information may also have a normal form representation. 0 D.A nite static game with complete information cannot have an extensive form representation. \fWhich of the following statements about the classic Cournot duopolyr model is incorrect? The two rms decide on their prices and let their quantities be dictated demand conditions. 0 The products of the two firms are homogeneous. Q There exist examples that have unique Nash equilibrium points. 0 It is a static game with complete information. Which one of the following statements about Cournot oligopoly model with N rms is incorrect? The result with unspecifed N firms can be applied to N='l. Q If N>'l and there exists a unique Nash equilibrium. then the market price cannot depend on N. O lfthe model is symmetric and there exists a unique Nash equilibrium and N approaches innity. then the market price approaches to the marginal cost, i.e., the perfectly competitive price. 0 The result with unspecified N rms can be applied to N approaching infinity
