Answer: A
Step-by-step explanation:
In this picture from your question, we can see two opposite teams where one team that is red is holding the ball and the other team is without it.
- According to game rules, the team on defense is always the team without the ball and that is why A is a correct answer, and B is an incorrect answer.
C, and D are also incorrect answers because both teams or neither team cannot be correct answers because they are not the same in this case since one team is having the ball.
