We will use the best response strategies to solve for the Nash equilibrium:
Best response of player 1:
Player 1 chooses U when player 2 chooses L
Player 1 chooses D when player 2 chooses C
Player 1 chooses D when player 2 chooses R
Best response of player 2:
Player 2 chooses L when player 1 chooses U
Player 2 chooses R when player 1 chooses M
Player 2 chooses L when player 1 chooses D
Thus, from the best responses, it is clear that there is a unique Nash equilibrium in which Player 1 chooses U and player 2 chooses L.
No, this is not Pareto efficient as the point (M, C) gives more payoff to both player 1 and player 2 and will thus pareto dominate the point (U, L)
