Correct option is C
Concept Used:In magnetic circuits, reluctance (R) is analogous to resistance in electrical circuits and is given by:R=μAlWhere,l=length of the magnetic pathμ=permeability of the materialA=cross-sectional areaFor parallel magnetic circuits, the total reluctance behaves similar to resistors in parallel:Rtotal1=R11+R21If both paths have equal reluctance:Rtotal=2RWhen two identical magnetic paths are in parallel, the magnetic flux splits equally, and each path effectively offers half the total reluctance. This improves the overall flux conduction capacity of the circuit.
