The lower value is the guaranteed result for Player I, the upper value is the guaranteed result for Player II. Player I, by choosing a row, maximizes the obtained element. Considering this, player needs to analyze each row to find the lower value on each row and then choosing the maximum among those numbers will give him the result. Each row has the lower value -6, -3 and -4 respectively. So max {-3, -4, -6} =-3 is obtained hence the correct answer is B.
