One method for recovering tin from obsolete printed circuit boards is to dissolve it in a combination of concentrated hydrochloric acid and concentrated nitric acid. The tin dissolves because it reacts with this mixture of concentrated acids. $\text{Sn} + 4\text{HCl} + 2\text{HNO}_3 \rightarrow \text{SnCl}_4 + \text{NO}_2 + \text{NO} + 3\text{H}_2\text{O}$ Which of the following statements about this reaction are correct?
- A1, 2 and 3 are correct
- B1 and 2 only are correct
- C2 and 3 only are correct
- D1 only is correct
