An electric current is constituted by the flow of
The correct option is B electrons.
Explanation for the correct option(s):
option b: electrons
Electric current is the amount of electric charge flowing through a unit area per second. In metallic wires, the flow of negatively charged particles called electrons constitutes the electric current.
Explanation for the incorrect option(s):
option a: neutrons
Neutrons are uncharged particles. Electric current is constituted by the flow of negatively charged particles.
option c: protons
Protons are positively charged particles and have less mobility than electrons. So they do not constitute a current.
option d: any one of them
Only electrons constitute the electric current.
Thus, an electric current is constituted by the flow of electrons. Hence option b is correct.
