Solution

The correct option is A $A = F e C l_{2}, B = H_{2}$
Active metals with higher tendency to lose electron than hydrogen can displace hydrogen gas with dilute mineral acid.
$F e + 2 d i l . H C l \to F e C l_{2} + H_{2}$

Preparation of dihydrogen:
By the action of metals with acids.
Active metals have higher tendency to lose electron than hydrogen, it can displace hydrogen gas with dilute mineral acid
$F e + 2 d i l . H C l ⟶ F e C l_{2} + H_{2}$
$C u + d i l . H_{2} S O_{4} ⟶ N o r e a c t i o n$
