FeCl_3 + K_4[Fe(CN)_6] to ?

[Fe(CN)_(6)]^(4-) is a coordination complex ion. Is the complex ion diamagnetic or paramagnetic ?

Assertion : [Fe(CN)_6]^(3-) is weakly paramagnetic while [Fe(CN)_6]^(4-) is diamagnetic. Reason : [Fe(CN)_6]^(3-) has +3 oxidation state while [Fe(CN)_6]^(4-) has +2 oxidation state.

Assertion: [Fe(CN)_6]^(3-) is weakly paramagnetic while [Fe(CN)_6]^(4-) is diamagnetic Reason: Both [Fe(CN)_6]^(3-) and [Fe(CN)_6]^(4-) involve d^2sp^3 hybridisation. In [Fe(CN)_6]^(3-) singly occupied d-orbital is available but in [Fe(CN)_6]^(4-) paired electrons are present

Hydrogen peroxide oxidises ["Fe"("CN")_(6)]^(4-) to ["Fe"("CN")_(6)]^(3-) in acidic medium but reduces ["Fe"("CN")_(6)]^(3-) to ["Fe"("CN")_(6)]^(4-) in alkaline medium. The other products formed are, respectively-
