A Simply Supported Beam Is Loaded as Shown in the Figure

A simply supported beam is loaded as shown in the figure. The bending moment at point C is approximately: (A) $5.7 \mathrm{kN} \cdot \mathrm{m}$
(B) $6.1 \mathrm{kN} \cdot \mathrm{m}$
(C) $6.8 \mathrm{kN} \cdot \mathrm{m}$
(D) $9.7 \mathrm{kN} \cdot \mathrm{m}$
