Solution

The correct option is C Both A and B
HCl can be prepared by any on the 2 methods:

1) By synthesis
Moist hydrogen gas combines with chlorine in the presence of diffused sunlight.
$H_{2} + {C l}_{2} s u n l i g h t - ---- \to d i f f u s e d 2 H C l$

2) By heating metallic chloride with conc. sulphuric acid.
$M e t a l c h l o r i d e + S u l p h u r i c a c i d (c o n c .) \to S a l t + H C l$
eg:
$N a C l + H_{2} {S O}_{4} {< 200}^{\circ} C - --- \to {N a H S O}_{4} + {H C l}_{(g)}$
