What are the steps required in sequence to solve a circuit using superposition theorem?(a) Select any one source and short circuit all other voltage sources.(b) Find out the current or voltage across the required element, due to the source under consideration.(c) Open all current sources, if the internal impedance is not known. If known replace them by their impedances.(d) Add all the individual effects produced by individual sources to obtain the total current in or across the voltage element.Code :

• A. (a), (c), (b), (d)
• B. (a), (b), (c), (d)
• C. (c), (a), (b), (d)
• D. (a), (d), (c), (b)
