    There are 9 married couples. Therefore, there will be 9 men and 9 women. 
    First, let us select the 2 men. 
    2 men can be selected in 9C2 = 36 ways.

    Now, the wives of these 2 men cannot be selected. Therefore, we have to select 2 women from the remaining 7 women. 
    2 women can be selected in 7C2 = 21 ways.

    We have selected 2 men and 2 women. A team should consist of one man and one woman. Therefore, the 2 teams can be formed in 2 ways. 

    Therefore, the total number of ways in which the team can be selected is 36*21*2 = 1512.
    Therefore, option B is the right answer.
