Solution

The correct option is C Metal $+$ dilute nitric acid
Dihydrogen gas is not produced (under normal conditions) in the reaction metal $+$ dilute nitric acid. For example, the action of dilute nitric acid on copper gives $N O$ gas and the action of dilute nitric acid on zinc gives $N_{2} O$ gas.
$3 C u + 8 H N O_{3} ( dilute ) \to 3 C u (N O_{3})_{2} + 2 N O + 4 H_{2} O$
$4 Z n + 10 H N O_{3} ( dilute ) \to 4 Z n (N O_{3})_{2} + N_{2} O + 5 H_{2} O$
