The single line diagram of the simple system is shown in figure the corresponding reactance diagram is

• A. C
• B. A
• C. D
• D. B

Answer: (A)

Simple logic of reactance diagram is that simplified equivalent circuit of power system in which the various components of power system are represented by their reactance.
The reactance diagram can be obtained from impedance diagram if all the resistive components are neglected.
So, from figure each of the component is represented by its reactance.
