(C) The deposition of metals during electrolysis occurs in the order of their reduction potentials,starting from the highest reduction potential to the lowest reduction potential.Given standard reduction potentials: $E_A^\circ = -1.2 \ V$,$E_B^\circ = 0.6 \ V$,$E_C^\circ = 0.85 \ V$,and $E_D^\circ = -0.76 \ V$.Arranging these in decreasing order: $0.85 \ V (C) > 0.6 \ V (B) > -0.76 \ V (D) > -1.2 \ V (A)$.Thus,the sequence of deposition is $C, B, D, A$.
