The expression written in simplest form means that it cannot be further reduced or simplified. In the given options, A, C, and D can still be simplified because their fractions can be further reduced. A becomes (7/3) - (2/3) = (5/3), C becomes (19/3) = (18/3) + (1/3) = (6/3) + (1/3) = (7/3), and D becomes (8/3) = (6/3) + (2/3) = (2) + (2/3). Therefore, the only option that is already in its simplest form is B, (21/3) = (7/3), making it the correct answer.
