Kirchhoff ’s junction rule is a reflection of


The Kirchhoff’s junction rule is based on the fact that at a junction, the amount of the current entering a junction is equal to the amount leaving it. This means there should be a conservation of charge at all points in a conductor.KIRCHOFF.png

This, in corollary, also states that there shouldn’t be any accumulation of charges in the junction else the amounts may differ. So, option (b) and(d) are correct.
