Consider two chemical reactions \( (A) \) and \( (B) \) that take place during metallurgical process:
\( (A)\displaystyle \text{ZnCO}_{3\text{ (s)}} \xrightarrow{\Delta} \text{ZnO}_{\text{ (s)}} + \text{CO}_{2\text{ (g)}}\)
\( (B)\displaystyle 2\text{ZnS}_{\text{ (s)}} + 3\text{O}_{2\text{ (g)}} \xrightarrow{\Delta} 2\text{ZnO}_{\text{ (s)}} + 2\text{SO}_{2\text{ (g)}} \)
The correct option of names given to them respectively is:
