In the diagram shown the ground is amooth and `F_(1)` & `F_(2)` are both horizontal forces. The mass of the upper block is 10 kg while that of lower block is `15 kg`. The correct statement is :

Options

A. `m_(1)` experiences frictional force towards west only if `F_(1) gt F_(2)`
B. If `F_(1) ne F_(2)` then it is possible to keep the system in equilibrium for certain suitable values of `F_(1) & F_(2)`
C. If the system is to remain in equilibrium then `F_(1)` must be equal to `F_(2)` & `F_(2) lt 10N`
D. If `F_(1)/m_(1)=F_(2)/m_(2)` then frictional force between the blocks is zero
