total matches one team plays in each group : 4c2 = 6
total groups = 8
total group matches : 8 * 6 = 48 IMO C

I arrived at C as well, but am confused by your combination. How would the number of matches a team plays in each group =6 and why would the combo = 4c2?

e.g.
Group A Pairings: (1 v 2, 1 v 3, 1 v 4), (2 v 1, 2 v 3, 2 v 4), (3 v 1, 3 v 2, 3 v 4) (4 v 1, 4 v 2, 4 v 3) and then subtract redundant combinations... leaving you with (1 v 2, 1 v 3, 1 v 4), (2 v 3, 2 v 4) and (3 v 4)

6 unique matches in each group * 8 groups =48

4c2 : means that in a group of 4 teams , each team would play each other once so total no. of matches in the group would played would be 6 or 4c2..

=>

Each group plays 4C2 = 6 games and we have 8 groups.
Thus, the group stage includes 6*8 = 48 games.
