Which of the following is TRUE in case of Substitution theorem?

The initial condition of the rest of the circuit changes, if a network element is replaced by a voltage source having an equal voltage as the voltage across the element at every instant of time.

The initial condition of the rest of the circuit changes, if a network element is replaced by a voltage source having an equal current as the voltage across the element at every instant of time.

The initial condition of the rest of the circuit remains same, if a network element is replaced by a voltage source having an equal voltage as the voltage across the element at every instant of time.

The initial condition of the rest of the circuit changes, if a network element is replaced by a voltage source having an equal voltage as the current across the element at every instant of time.
