It is a displacement reaction. Copper, being more reactive than silver, displaces silver from silver nitrate solution:
$$\text{Cu(s)} + 2\text{AgNO}_3\text{(aq)} \rightarrow \text{Cu(NO}_3)_2\text{(aq)} + 2\text{Ag(s)}$$

Examiners expect both the name of the reaction type and the balanced equation. Since this is 1 mark, giving only one earns half credit. Note that copper displaces silver because Cu is higher in the reactivity series than Ag. Balance carefully: 2 AgNO₃ on the left, 2 Ag on the right.
