Consider a Voltaic Cell That Corresponds to the Following Reaction $\rightarrow$

Consider a voltaic cell that corresponds to the following reaction: Mg(s) + Sn²⁺(aq) $\rightarrow$ Mg²⁺(aq) + Sn(s) Which of the following statements is correct?

A) Magnesium is the oxidizing agent.
B) The Sn²⁺ solution must be in the half-cell with the magnesium electrode.
C) No salt bridge is necessary, since the charge is 2+ on both sides of the equation.
D) The tin electrode is the cathode.
E) Four electrons will be transferred per atom of magnesium that reacts.
