The correct answer is C. Conductance.
Conductance is the ability of a material to allow the flow of electric current. It is measured in siemens (S). The higher the conductance, the easier it is for current to flow through the material.
Resistance is the opposite of conductance. It is the measure of how difficult it is for current to flow through a material. It is measured in ohms (Ω). The higher the resistance, the more difficult it is for current to flow through the material.
Reluctance is a measure of how difficult it is for magnetic flux to pass through a material. It is measured in ampere-turns per weber (AT/Wb). The higher the reluctance, the more difficult it is for magnetic flux to pass through the material.
Inductance is a measure of how much energy is stored in a magnetic field when current flows through a conductor. It is measured in henries (H). The higher the inductance, the more energy is stored in the magnetic field.
In conclusion, the property of a conductor due to which it passes current is called conductance.
