Correct option is B
Incorrect, because "School" is another institution, not a person related to "College."
Correct, as "Student" is a person who studies in a "College," similar to "Patient" who goes to a "Hospital."
Incorrect, as "Study" is an action, not a person, and thus doesn't match the person-place relationship.
Incorrect, because a "Doctor" is associated with "Hospital," not "College."
