Correct option is C
In a magnetic circuit, magnetic flux (Φ) is analogous to electric current (I) in an electric circuit. Just as current flows through an electric circuit due to a potential difference (voltage), magnetic flux flows through a magnetic circuit due to a magnetomotive force (MMF). Similarly, just as electric current is opposed by resistance, magnetic flux is opposed by reluctance in a magnetic circuit. Therefore, the correct analogy is that magnetic flux is equivalent to current in an electric circuit.
