Can anyone help explain this answer D? I could not understand why D is the correct answer.

Thank you.

Good question.

There are exactly five employees. The first rule states that there is exactly one president. The second rule indicates that there must be at least one manager, and that this manager is supervised by the president.

Since the president supervises at least one manager, each manager supervises at least one employee, and F does not supervise anyone, F must be a technician.

So we have exactly one president, at least one manager, and at least one technician. This accounts for three of the employees. The remaining two employees cannot both be managers, because that would give us three managers and only one technician. Two of the managers would have nobody to supervise, violating the third rule. So we must either have one manager and three technicians, or two managers and two technicians.

You can see all of this represented by the diagram that Brian Birdwell shared in this thread: https://www.manhattanprep.com/lsat/forums/diagram-t996.html.

If F, who must be a technician, is supervised directly by the president, there cannot be two managers. This would leave only one other employee to be a technician, so one of the managers would not have anyone to supervise. So, in this situation, there must be exactly one manager. So, choice (D) is correct.
