Copper is an unreactive metal and doesn’t react in normal circumstances with dilute acids. However it does react with nitric acid. Which of the following equations represent how Copper reacts with DILUTE nitric acid?

Question

$\begin{array}{1 1}(A) 3Cu + 8HNO_3 \rightarrow 3Cu(NO_3)_2 + 2NO + 4H_2O \\ (B) Cu + 4HNO_3 \rightarrow Cu(NO_3)_2 + 2NO + 2H_2O \\ (C) 3Cu + 8HNO_3 \rightarrow Cu(NO_3)_4 + NO + 2H_2O \\ (D) Cu + 4HNO_3 \rightarrow 3Cu(NO_3)_2 + 2NO + 4H_2O \end{array} $
