Consider the T-period Prisoner's Dilemma game illustrated in the video above. Which of the following is FALSE? O A. There exists a unique subgame perfect equilibrium O B. "If T=2, player 1's strategies are as follows: (C,CCCC), (C,CCCD), (C,CCDC), ., (C,DDDD), (D,CCCC), ., (D, DDDD); there are 28 = 32 many strategies of player 1 C. Let T=3 and the discount factor is 0.5. The average discounted (period-1) payoff of player 1 from the history (C,C) in period 1, (D,C) in period 2 and (D,D) in period 3 is 1.25
