Observe the figure and find the correct relation from the four given options?

i1 + i2 + i4 = i3 + i5 + i6

i4 + i2 + i3 = i1 + i5 + i6

i1 + i2 + i6 = i4 + i5 + i3

i1 + i2 + i3 = i4 + i5 + i6

i1 + i2 + i4 = i3 + i5 + i6

i4 + i2 + i3 = i1 + i5 + i6

i1 + i2 + i6 = i4 + i5 + i3

i1 + i2 + i3 = i4 + i5 + i6
