Correct Answer - Option 4 : L, N and P
1) N and O are in different teams.
2) M is sitting facing N. From these two lines it is clear that M and O is in same team and N is in different team.
Option 1: N, L and M → N cannot be in the same team as M. They both are facing each other
Option 2: O, K and N → It is clearly given N and O are in different teams.
Option 3: K, M and P → With M there should be O in the team so K, M and P is not possible
Option 4: L, N and P → N is sitting to the immediate right of L and P is at the corner so this is possible team.
Hence, L, N and P is the correct answer.
