Alice and Betsy are playing a game in which each can play either of two strategies, "leave" or "stay". If both play the strategy "leave", then each gets a payoff of $100. If both play the strategy "stay" then each gets a payoff of $200. If one plays "stay" and the other plays "leave", then the one who plays "stay" gets a payoff off $C and one who plays "leave" gets a payoff of $D. When is the outcome where both play "leave" a Nash equilibrium.
A. Never, since $200>$100
B. When 100>C and D>200 but not when 200>D
C. When D>C and C>$100
D. Whenever D<200 E. Whenever 100>C
