Suppose IA, IB and IC are a set of unbalanced current phasors in a three-phase system. The phase-B zero-sequence current IB0 = 0.1∠0° p.u. If phase-A current IA = 1.1∠0° p.u and phase-C current IC = (1∠120° + 0.1) p.u., then IB in p.u. is
A
1∠240° − 0.1∠0°
B
1.1∠240° − 0.1∠0°
C
1.1∠−120° + 0.1∠0°
D
1∠−120° + 0.1∠0°

Correct : d
