Answer must be charge. Because in semiconductors current is due to holes and electrons both. Holes are the absence of electrons which keeps shifting to give a flow of current. Hall experiment has also proved that holes exist. Hole is actually a controversial concept. And in electrolytic batteries current arises due to flow of ions.

But if you considered p-type semiconductor or uni polar device lik mosfet the current is due to flow of holes(+ve charge)too. so why can't the answer be option c ie charge?

Hole is a vacancy means absence of -ve charge, which is created at the place of electron when it leaves its original place, it's not a particle like proton.

Current is nothing but flow of charge not only electrons. If we consider electrolyte in which current is due to the flow of ions rather than electrons.

Current is nothing but flow of charges not an electron, but electron flow will be call it as charge. So the answer is charge.

Current is flowing of charge particles. Here not mention the conventional current and electric current so answer is charges.

Current is defined as flow of charge. The electrons charge is negative (-) to flow the negative to positive.

Uni-polar means it can carry only one type of charge carriers so he doesn't ask one type charge carrier.

Electronics engineering deals with the movement of electron and holes both so the answer must be charge.

Electrical current flow is the movement of electron from lower to higher potential.
