Stones A, B, C and D of same masses are thrown on a wall. Acceleration produced in them are \[2m/se{{c}^{2}},\text{ }3\text{ }m/se{{c}^{2}},\text{ }5\text{ }m/se{{c}^{2}},\text{ }4\text{ }m/se{{c}^{2}}\] respectively. Arrange the force exerted by the stones in descending order.

A. \[{{f}_{A}}>{{f}_{B}}>{{f}_{C}}>{{f}_{D}}\]
B.  \[{{f}_{D}}>{{f}_{C}}>{{f}_{B}}>{{f}_{A}}\]
C.  there is no frictional force between the box and the ground
D. \[{{f}_{C}}>{{f}_{D}}>{{f}_{B}}>{{f}_{A}}\]
