Current in a circuit flows:
(A) In direction from high potential to low potential
(B) In direction from low potential to high potential
(C) In direction of flows of electrons
(D) In any direction.

Hint:
Electrons always flow in opposite directions.
OR
The direction of an electric current is by convention the direction in which a positive charge would move.

Complete Step by Step Answer
Electric current flows from higher electric potential to lower electric potential.

If we put metal in an electrical circuit. As we know that current flows from positive terminal to negative terminal.
 Then a positive terminal flows in the current direction. If electrons are present in metal then they flow opposite to applied current which means current flows in the direction of electric field.
Positive terminal is considered as high potential and negative charge is considered as low potential. The direction of motion of positive charge is always high potential to low potential but direction of motion of negative charge is always from low potential to high potential.
Which could be represented as
$V = - \phi \vec E.dr$
So we can say that current flows the same as direction of field and high potential to low potential.
Therefore we conclude that direction of current is always opposite to the direction of current that is high potential to low potential.

Hence the correct option is A.

Note:
For the current to flow, it required a circuit which is a closed loop of a conducting material. The circuit consists of wires which are connected end to end and the electrons flow in the same direction.
