sees the reasons for people's behaviors is the correct answer because Coach Tanner seems to know that it is not his physical condition that is holding Austin back.
I could not find the passage that is missing in your question but I have found online that the right answer is D) which is also the most and only logic answer to this question since in the question I can see that coach Tanner is a kind person.
Because of the kindness that is mentioned in the question he cannot be mean or unsympathetic which we can see in answer A) and other two answers B) and C) cannot also be correct because they are not representing characteristics of a kind person.
