The kirchhoff's first law

\left( {\sum i = 0} \right)

and second law 

\left( {\sum {\mkern 1mu} {\mkern 1mu} iR = 0} \right)

where the symbols have their usual meanings, are respectively based on

View answer and explanation

Correct option: D

Conservation of charge, conservation of energy

Option D is correct because Kirchhoff's first law (junction rule) is based on the conservation of charge, and Kirchhoff's second law (loop rule) is based on the conservation of energy.
