If V_a0, V_a1, V_a2 are sequence components of V_a and I_a0, I_a1, I_a2 are sequence components of I_a, then total 3 phase power P is given by

P = V_a0I_a0 + V_a1I_a1 + V_a2I_a2

P = V_a0I_a0 + V_a1I_a1 + V_a2I_a2^*

P = 3(V_a0I_a0 + V_a1I_a1 + V_a2I_a2)

P = 3(V_a0I_a0 + V_a1I_a1 + V_a2I_a2^*)

Answer : Option D

Explanation :

There are a total of 9 components (Three for each phase). Moreover, in general, P = VI^*.
