I do not see a conflict between the diagram and text either, but am unclear on weather or not you are to include gravity, I would guess yes, else why tell you the mass. Force and weight are almost always in N not Kg ( mass ). It just says the weights act on the bean, not how, they could not be placed on it as they would both point down. So strings and pulleys may be involved but not show. The fact that the forces are from weights also suggest a gravitational field. I would give a C to the author of the question.
