The first step in responding to any sports injury is to
a. remove the danger that lead to the injury
b. ensure that the player's air way is not obstructed
c. begin chest compressions for cpr
d. ask the player to stop playing the sport

If you're talking about ANY sports injury, think about which options can NOT be right.  Option B can't be right--say the player broke his ankle on a rock.  Would his airway be obstructed?  No.  What about Option C?  If the player broke his ankle, again, he doesn't need CPR.  And asking the player to stop playing the sport (option D) wouldn't make sense.  Everyone can get injured while playing, and that is certainly not the FIRST step to do when facing an injury.

Think about option A.  The #1 thing you need to do when dealing with an injury is to make sure it can't get you, the victim, or anyone else hurt.  Therefore, it seems to me that the correct answer would be A.
