Answer:
A is true
Explanation:
Each baseball team in a baseball league has 14 players.
For a team of baseball = 14 players 
For 2 team of baseball = 14 x 2 = 28 players 
For t number of of team = 14 x t = 14t players. 
But total number of players that signed up to play is 56
Therefore, 14t must be equal to 56
14t = 56 ( True equation) 
Now we will solve for t 
Divide both sides by t 
t = 4 
From 56 players we can make 4 teams. 
Hence, A is true statements.
