What is oxidized and what is reduced in this reaction?Cu(s) + 2AgNO3(aq) → Cu(NO3)2(aq) + 2Ag(s)

Copper changes from an oxidation state of 0 in Cu(s) to +2 in Cu(NO₃)₂, so copper loses electrons and is oxidized. Silver changes from +1 in AgNO₃ to 0 in Ag(s), so silver gains electrons and is reduced. Therefore, the correct choice is “Ag is reduced and Cu is oxidized.”
