A Voltaic Cell Is Prepared in Which Aluminum Metal Is $\rightarrow$

A voltaic cell is prepared in which aluminum metal is oxidized to Al³⁺, and nickel(II) is reduced to nickel metal.Which of the following represents the correctly balanced equation for this reaction?

A) Al(s) + Ni²⁺(aq) $\rightarrow$ Al³⁺(aq) + Ni(s)
B) Al(s) + 2Ni²⁺(aq) $\rightarrow$ Al³⁺(aq) + 2Ni(s)
C) 2Al(s) + 3Ni²⁺(aq) $\rightarrow$ 2Al³⁺(aq) + 3Ni(s)
D) Al³⁺(aq) + 2Ni(s) $\rightarrow$ Al(s) + 2Ni²⁺(aq)
E) 2Al³⁺(aq) + 3Ni(s) $\rightarrow$ 2Al(s) + 3Ni²⁺(aq)
