Consider a cooperative game with N=3N=3 and v(1)=v(2)=v(3)=1v(1)=v(2)=v(3)=1 and v(?)=0v(?)=0.

With which of the following revenue functions the game is superadditive?

Select answer:

a. None of the options. b. v(1, 2) = 0, v(1, 3) = 4, v(2, 3) = 5, v(1, 2, 3) = 7, v(0) = 0; c. v(1, 2) = 3, v(1, 3) = 4, v(2, 3) = 5, v(1, 2, 3) = 5, v(0) = 0; d. v(1, 2) = 3, v(1, 3) = 4, v(2, 3) = 5, v(1, 2, 3) = 7, v(0) = 0
