The direction of current in a conductor is in the direction of flow of

Explanation:

Conventionally, the current flows in the direction of flow of positive charge or opposite to the flow of negative charge (electrons).
In reality, positive charges in a conductor do not flow. It is free electrons that constitute a current.
Therefore,
The direction of current in a conductor is in the direction of flow of Positive charges.

Final Answer:

Hence, Option C is correct i.e, Positive charges
