A uniform rod of mass \(M\) and length \(L\) is attached to a frictionless pivot on a ceiling. A student pulls the bottom end of the rod to the right with a constant horizontal force \(F\), holding the rod at a fixed angle \(\theta\) with the vertical as shown.

Which of the following free-body diagrams best represents the forces exerted on the rod while it is held in this position? (Note: \(F_{px}\) and \(F_{py}\) represent the horizontal and vertical components of the force exerted by the pivot on the rod.)
