In the reaction:
A2+(aq) + B(s) --> B2+(aq) + A(s)
A. A2+ is oxidized
B. B2+ is reduced
C. B is the reducing agent
D. A is reduced
E. All of the above

I don't understand how you can differentiate between C and D. My professor told me C is the correct answer. Someone please help me out, I'm stressing way more than I should about this one single problem lol

D is incorrect because it's not A that's being reduced. It's A2+ that is being reduced.
