Answer» Correct option (C) AS, Al, Na and Pb Explanation: Silver cannot displace hydrogen from dilute acid.The! reaction of aluminium with hydrochloric acid is exothermic.Sodium is highly reactive so, reaction is explosive. Lead is slightly more reactive than hydrogen hence, only some gas bubbles are seen.
