Equation 1: X (s) + CuCl2 (aq) → Cu(s) + XCI2 (aq)
Equation 2: X (s) + AlCl3 (aq) → no reaction

Which of the following represents a possible identity of metal X and provides the correct justification? Explain your reasoning.

a. Pt, because Pt is oxidized more easily than both Al and Cu.
b. Fe, because Fe is oxidized more easily than both Al and Cu.
c. Fe, because Fe is oxidized more easily than Cu but less easily than Al.
d. Pt, because Pt is oxidized more easily than Cu but less easily than Al.
