C. Electoral College
Explanation:
The infringement of constitutional laws is known as compromising the constitution. In the examples given here, the first two are obviously not permissible by the constitution as they pertain to slave trade in some form or measure which has been completely outlawed in all forms. 
The fourth one is a federal and state issue and comes under the jurisdiction of the interstate relations. Although the federals can put regulations on interstate trade they have no right of direct control over it. 
 
        
             
        
        
        
Answer:
The correct answer would be, Restrict the other team from doing goal. 
Explanation:
Hockey is a game in which there are two teams, each of which consists of 11 players. Both teams have an area where teams have to mark goals. Both teams have their goal keepers in that area. Players play with each other by passing ball to other players of their own team and making it to the goal area of the other team to hit a goal to get a point. So if it seems impossible for a player to attempt a goal then he should at once change his strategy and has to play a game in which he just restricts the players of the other team from scoring a goal. In this way, if he is not able to mark a goal, the other team will also not get a chance to attempt the goal.
