(3) Statement I is correct and Statement II is incorrect
(4) Statement I is incorrect and Statement II is correct
Statement-I: \( \mathrm{KCN} \) gives \( \mathrm{K}_{3}\left[\mathrm{Cu}\left(\mathrm{CN}_{4}\right)\right] \) complex compound with \( \mathrm{CuSO}_{4} \) solution.
Statement-II: \( \mathrm{KCN} \) in \( \mathrm{CuSO}_{4} \) solution reduces \( \mathrm{Cu}^{2+} \) to \( \mathrm{Cu}^{+} \) and then form a complex compound.
