Consider a situation with two players in which the row player's strategy set is {A, B, C, D}and the column player's is {W, X, Y, Z}. (a) Construct a strategic form game for this situation with exactly 3 Nash equilibrium strategy combinations, one of which is Pareto-optimal, and two of which are not. (b) Identify all the Pareto-optimal strategy combinations in the game you constructed.
