Please explain the answer so that I can understand

2. Suppose Rowena and Colin are in the following situation (monetary payoffs): L R T 3,3 1, 4 B 4, 1 0,0 (a) Suppose both Rowena and Colin arc selfish and risk-neutral. Does the game have any pure strategy Nash equilibria? (b) Suppose Rowena and Colin cannot talk to each other. Do you think they will play a pure-strategy equilibrium? (c) Suppose Rowena is selfish and risk-neutral, but Colin has the altruistic utility function Uc = cc + CR/2. Can you find any pure-strategy Nash equilibria now? (d) Suppose Rowena also has a similarly altruistic utility function UR = CR + cc/2. Can you find any purc-strategy Nash equilibria now
