Solution

The correct option is A positive electrode to the negative electrode
According to the convention, the direction of the current is opposite to the flow of negative charges (electrons). We take the direction of the flow of positive charges as the direction of the current. Negative charges flow from the negative electrode of a cell to the positive electrode, and hence we can say positive charges flow from the positive electrode to the negative electrode. Thus, by convention, the electric current flows from the positive electrode to the negative electrode.
