2 mL each of Conc. HCl, HNO₃ and a mixture of conc. HCl, & conc. HNO₃, in the ratio of 3:1 were taken in test tubes labelled as A, B, and C. A small piece of metal was put in each test tube. No change occurred in test tubes A & B, but the metal got dissolved in test tube C. The metal could be:
[B] Au
[B] Au
