Solution

The correct option is B Aluminium
Metals on reaction with acids produce respective salts and hydrogen gas. Aluminium reacts with dilute hydrochloric acid to form aluminium chloride and hydrogen. The reaction involved is:

$2 Al (s) + 6 HCl (aq) \to 2 {AlCl}_{3} (aq) + 3 H_{2} (g)$

Since, gold and silver are least reactive they do not react with acids.
