Solution

The correct options are
A A: Electric current
B B: Electron flow
The direction of electric current is in the opposite direction of electrons, i.e. in the opposite direction of flow of negative charges. The electrons flow from negative to positive terminal of cell. Hence, the direction of current is taken from positive to negative terminal of cell. The current flows from higher to lower potential in the external circuit.
