(1) If a new team, team Z, is formed from teams X and Y it will have an average height of 5 feet 9 inches.
(2) There are 12 players on team X.


(1) We can see that the combined average of team Z (which comprises of members from X and Y) is 5 feet 9 inches, and this value is closer to the average height of team Y (5 feet 10 inches) than it is to the average height of team X (5 feet 7 inches). This means there are more players in team Y than there are in team X. Sufficient.

(2) 12 players in team X, but nothing mentioned about Y, or nothing about combined average. Insufficient.

Hence A answer
