Hello. You did not show the answer options, which makes it impossible for me to answer you accurately. However, I will try to help you in the best possible way.
An argumentative essay is an essay in which the author presents arguments that convey his or her opinion on the subject to which the essay refers. In this case, as you have shown that Zachary has an interest in football, we can assume that he will write an essay showing his opinion on something related to football. This essay can show what he thinks and what his opinion is about a player, a game, a team, a coach, or anything else related to football. The important thing is that he is able to argue, that is, to express an opinion on it.
