Detailed Solution

Concept- Electrical current is the flow of electric charge in its most basic form. Electric current is measured in amperes (A), which are widely regarded as the standard unit of measurement. One ampere is equal to one coulomb of charge flowing through a specific conductor in one second. The strongest electrical conductors, according to conventional wisdom, are metal wires.
In essence, metal wires are conductors that make it simple for current to flow through them. The atoms that make up conductive materials have loosely bound negatively charged electrons. We shall use atom's electrons as our charge carriers because every electron in an atom has a negative charge. Electric current is created when a charge is carried across metal conductors.
Now let's examine each alternative to determine which might be the potential solution.
Hence, option 1- Electrons is the correct answer.
