Al(s) | Al³⁺(aq) || Ni²⁺(aq) | Ni(s)
Which of the following represents the correctly balanced spontaneous reaction equation for the cell?

A) Ni²⁺(aq) + Al(s) $\to$ Al³⁺(aq) + Ni(s)
B) 3Ni²⁺(aq) + 2Al(s) $\to$ 2Al³⁺(aq) + 3Ni(s)
C) Ni(s) + Al³⁺(aq) $\to$ Ni²⁺(aq) + Al(s)
D) 3Ni(s) + 2Al³⁺(aq) $\to$ 3Ni²⁺(aq) + 2Al(s)
E) None of these choices is correct.
