Consider two chemical reactions (A) and (B) that take place during metallurgical process:

(A) $ZnC{O}_{3\left(s\right)}\stackrel{\Delta }{\to }Zn{O}_{\left(s\right)}+C{O}_{2\left(g\right)}$                             

(B)  $2Zn{S}_{\left(s\right)}+3O_{2\left(g\right)}\stackrel{\Delta }{\to }2Zn{O}_{\left(s\right)}+2S{O}_{2\left(g\right)}$

The correct option of names given to them respectively is:
