I would appreciate it if you could help me with these questions along with providing explanations

The following diagram provides a normal form representation of a two-person, one shot game. Jane L C R U 2, 5 3, 6 1, 2 Amy M 4, 4 7, 5 2, 1 D 3, 2 6, 3 4, 4 1. If Amy chooses to play strategy U, what is Jane's best response strategy? 2. Identify all the Nash equilibria to this game? 3. Suppose that this game is played sequentially with Amy playing first. Draw the sequential game and identify the Nash equilibrium
