Correct option is B
The Superposition Theorem is a principle for analyzing linear electrical circuits with multiple independent sources. It states that the total current or voltage in any part of a linear circuit is the sum of the currents or voltages produced by each independent source acting alone. To use this theorem, all but one source are deactivated (voltage sources are short-circuited and current sources are open-circuited), and the effect of the active source is calculated. This is repeated for each source, and the individual results are added together.
