This can be solved by assuming some numbers (satisfying the given criteria) for the teams.
Case 1: A < B
Number of members in Team A = 2
Number of members in Team B = 10
Number of ways a coach can be selected = 2c1 = 2 (10/5)
Number of ways a team of 9 people can be selected = 10c9 = 10
Case 2: A = B
Number of members in Team A = 11
Number of members in Team B = 11
Number of ways a coach can be selected = 11c1 = 11 (55/5)
Number of ways a team of 9 people can be selected = 11c9 = 55
Case 3: A > B
Number of members in Team A = 44
Number of members in Team B = 12
Number of ways a coach can be selected = 44c1 = 44 (220/5)
Number of ways a team of 9 people can be selected = 12c9 = 220
Therefore, answer is D
Case 1: A < B
Number of members in Team A = 2
Number of members in Team B = 10
Number of ways a coach can be selected = 2c1 = 2 (10/5)
Number of ways a team of 9 people can be selected = 10c9 = 10
Case 2: A = B
Number of members in Team A = 11
Number of members in Team B = 11
Number of ways a coach can be selected = 11c1 = 11 (55/5)
Number of ways a team of 9 people can be selected = 11c9 = 55
Case 3: A > B
Number of members in Team A = 44
Number of members in Team B = 12
Number of ways a coach can be selected = 44c1 = 44 (220/5)
Number of ways a team of 9 people can be selected = 12c9 = 220
Therefore, answer is D
