I wasn't able to understand the question...
Can someone explain the first payoff matrix. .... here only 1 player but payoff of both of them..

and in second who's row player and who's column player..

????

In the first game, the ideal strategy for the row player is to not enter, in which case it ends up with a payoff of 0 and the column player gets a payoff of 6.

In the second game, (enter, dove) is a pure strategy Nash equilibrium. The row player is better off with a payoff of 3 (as opposed to 0 in game 1) while the column player is worse off with a payoff of 3 (as opposed to 6 in game 1). Therefore, expansion of the game in terms of strategic options leaves one player better off at the expense of the other. Hence, (d).
