A non-uniform horizontal plank of mass \(M\) and length \(L\) has its center of mass located at a distance \(\dfrac{L}{3}\) from its left end. The plank rests horizontally on two vertical sawhorses: Sawhorse 1 at \(x = 0\) and Sawhorse 2 at \(x = L\). A point load of mass \(M\) is placed on the plank at position \(x\).

	\(F_{N,1}\) (Load at \(x = \dfrac{2}{3}L\))	\(F_{N,2}\) (Load at \(x = \dfrac{2}{3}L\))	\(F_{N,1}\) (Load at \(x = L\))
Row A	\(\dfrac{5}{6}Mg\)	\(\dfrac{7}{6}Mg\)	\(\dfrac{1}{2}Mg\)
Row B	\(\dfrac{4}{3}Mg\)	\(\dfrac{2}{3}Mg\)	\(\dfrac{5}{3}Mg\)
Row C	\(Mg\)	\(Mg\)	\(\dfrac{2}{3}Mg\)
Row D	\(\dfrac{1}{3}Mg\)	\(\dfrac{2}{3}Mg\)	\(0\)

Which row in the table correctly identifies the upward normal forces \(F_{N,1}\) and \(F_{N,2}\) exerted by the sawhorses for the given load positions?
