b. marcus, because single - celled organisms are not always living organisms.
c. ethan, because different cells perform different functions in a multi - celled organism.
d. marcus, because not all functions are performed within the cell of a single - celled organism.

Explanation:

In multi - celled organisms, cells have specialized functions. They do not all perform the same function. Ethan's statement that "each cell performs the same function" is incorrect.
