A uniform solid disc of mass `1` kg and radius `1m` is kept on a rough horizontal surface.
Two forces of magnitude `2N` and `4N` have been applied on the disc as shown in the figure. Linear acceleration of the center of mass of the disc is if there is no slipping is
A. `4m//s^(2)`
B. `2m//s^(2)`
C. `1m//s^(2)`
D. zero
