Solution
The correct option is C of positive charges In metals, there are plenty of free electrons which flow and make electric current. The direction of the current is taken opposite to the flow of electrons. Since electrons are negative charges, the direction opposite to the flow of electrons is the same as the direction of the flow of positive charges.
So conventionally, the direction of current is the same as the direction of the flow of positive charges.
