Consider the following half-cell reactions.
Al_(s) $\to$ Al³⁺_(aq) + 3e^-
Cu²⁺_(aq) + 2e^- $\to$ Cu_(s)

The overall equation for the reaction is

Al_(s) + Cu²⁺_(aq) $\to$ Al³⁺_(aq) + Cu_(s)

2Al_(s) + Cu²⁺_(aq) $\to$ 2Al_(aq) + Cu_(s)

2Al_(s) + 3Cu²⁺_(aq) $\to$ 3Cu_(s) + 2Al³⁺_(aq)

3Al_(s) + 2Cu²⁺_(aq) $\to$ Cu_(s) + 3Al³⁺_(aq)

Correct answer is C

Al_(s) $\to$ Al³⁺_(aq) + 3e^- ______(i)
Cu²⁺_(aq) + 2e^- $\to$ Cu_(s) ________(ii)

To balance the electrons, multiply equation (i) by 2 and equation (ii) by 3 and then add the resulting equations

2Al_(s) $\to$ 2Al³⁺_(aq) + 3e^-
3cu²⁺_(aq) + 6e^- $\to$ 3Cu_(s)
2Al_(s) + 3Cu²⁺_(aq) $\to$ 3Cu_(s) + 2Al³⁺_(aq)
