Correct answer: B
Explanation
Volunteer: A person who freely offers to take part in an enterprise or undertake a task without being paid.
Donor: A person who gives something (usually money, blood, or an organ) to a charity or cause, rather than performing work.
Trainee: A person undergoing training for a particular job or profession (usually paid, though sometimes at a lower rate).
