Ответ:
A. The net force was in their direction.
Explanation:
In the game of tug of war the two teams will pull the two ends of the rope with different forces.
When the two teams will pull the two ends of the rope then the team who win is the one who pull the rope towards them.
so here in order to win Team A we know that team A has to pull the rope towards them.
So it must have more force towards them.
So net force is always towards team A in order to win the game
So here correct answer will be
A. The net force was in their direction.
