As shown in the figure, the simply supported beam is subjected to various external loads. When the distributed external force acts on section AB, and its concentration is w = 1   kn / m, the maximum shear force and bending moment on the beam are 
A、3.2kN,  6.01kNm
B、3.2kN,  5.67kNm
C、1.83kN,  6.01kNm
D、1.83kN,  5.67kNm
