Respuesta :
The statement which best describes the action- reaction force in the given situation is the wall pushes on the skater when the skater pushes on the wall.
What is Newton's third law of motion ?
According to Newton's third law of motion every action is associated with an equal and opposite reaction. Thus, when we exert a force on the wall the wall exert a force in turn in equal magnitude but in opposite direction.
This law clearly explains the motion of an object by applying a force on another object like in the case of a rocket motion. In the given situation, the skater pushes the wall at the same time the wall in turn push him in opposite direction.
This opposite push exerted from the wall make him move upwards. Hence, option A is correct.

Your question is incomplete. But your complete question probably was:
A skater pushes off a wall and skates backward for a few meters before stopping.
Which statement best describes an action-reaction force pair in this situation?
The wall pushes on the skater when the skater pushes on the wall.
The wheels slow down, and the skater stops.
The skater exerts a force on the wall, and the wheels exert a force on the floor and begin
to turn
The friction of the floor decreases when the wheels roll on the floor.
