Best answer
Correct choice is (a) shear and pressure force acting on body

To explain I would say: Shear force and pressure force are most fundamental cause which generates aerodynamic forces. Shear forces typically seen as resisting forces which results in friction. Pressure force or pressure gradient will generate forces as well.
