Understanding the problem:
- There are 7 children in the family, 3 male (A, B, C) and 4 female (W, X, Y, Z).
- They need to form teams with 2 male children in each team.
- B cannot play with W, C cannot play with Z, and W cannot play with Y.

Solution:
- Since all 3 males need to be in the team, the combinations can be formed as follows:
- A & B
- A & C
- Therefore, there are 2 possible combinations of teams when all 3 males are selected.
Thus, the correct answer is option 'B' - 2 combinations.
