Answer:
Outreach
Explanation:
The three options provided are types of people i.e "children", "elderly", and "homeless". So, the fourth element too should be a type of people. Hence, "Finances", and "Conservation" are eliminated.
Out of "Students" and "Outreach", "outreach" would be better option;
Firstly because, children (age), elderly (age) homeless (location), and then fourth too should be about location i.e. "Outreach"
Secondly, because "students" is a sort of occupation, children may also be students. So, "Students" does not fit well with the three provided options.
The plot is always the overriding idea in fiction.
