Answer:
The answer is: b. Jamal, a senior captain of the football team and class treasurer.
Step-by-step explanation:
The first and third option aren't possible as normally these would be the opposite; negatively predisposed, as their activities and due to this, personality, is very different.

On the other hand, Jamal, who is a boy and shares similar activities as Sumatra, as well as age, for these reasons he is more likely to be positively predisposed.
