    Answer : Option C

    Explanation :

    Using Mesh analysis

    Loop 1 : 6 = 9i1 - 3i4 ...(i)

    Loop 2: 6 + 6 = - 6i2

    i2 = - 2A ...(ii)

    Loop 3: 6 = 9i3 - 3i4 ...(iii)

    Loop 4: 6 = 9i4 - 3i3 - 3i1 ...(iv)

    Solving the above equations simultaneously

    i1 = i3 = 1.1428 A

    i4 = 1.432 A

    ∴ ix = i4 - i3 = 0.2892 A.
