Which of the following product is formed when Cu reacts with dilute $H_{2}S{O}_4$?

Cu do not reacts with dilute $H_{2}S{O}_4$ .
Copper is less reactive than the hydrogen in the reactivity series. Hence, it does not displace hydrogen from dilute acid. However when copper is reacted with concentrated sulphuric acid, it gives out sulphur dioxide gas. 

The reaction of Cu with dilute sulphuric acid is
$\mathit{Cu}+H_{2}S{O}_4\left(\mathit{dil}\right)\to \mathit{No\; reaction}$
