Provide an appropriate response.In certain situations, a matrix game can be reduced to a smaller game by deleting certain rows and/or columns from the payoff matrix. The optimal strategy for the reduced game will then determine the optimal strategy for the original game. In what circumstances may a row or column be deleted from the payoff matrix?
A. A row may be deleted if it is recessive to some other row and a column may be deleted if it is dominant to some other column. B. A row may be deleted if it is dominant to some other row and a column may be deleted if it is recessive to some other column. C. A row may be deleted if it is dominant to some other row and a column may be deleted if it is dominant to some other column. D. A row may be deleted if it is recessive to some other row and a column may be deleted if it is recessive to some other column.
