When metal A is placed in a solution of metal ions B2+, a reaction occurs between A and B2+, and metal ions A2 + appear in the solution. When metal B is placed in acid solution, gas bubbles form on its surface. When metal A is placed in a solution of metal ions C2+, no reaction occurs. Which of the following reactions would not occur spontaneously?

A. C (s) + 2H + (aq) → H2 (g) + C2 + (aq)

B. C (s) + A2 + (aq) → A (s) + C2 + (aq)

C. B (s) + C2 + (aq) → C (s) + B2 + (aq)

D. A (s) + 2H + (aq) → H2 (g) + A2 + (aq)

E. B (s) + 2H + (aq) → H2 (g) + B2 + (aq)
