Correct option is B
Substitution Theorem:
· The Substitution Theorem states that in an electrical circuit, if a voltage source or a current source is replaced by an equivalent source (in terms of producing the same effects in the circuit), the overall behavior of the circuit remains unchanged.
· This theorem can be applied to both linear and nonlinear circuits because it does not rely on the linearity of the elements involved. It simply requires that the replacement source produces the same effect in the circuit as the original source.
