Match the extraction processes listed in column `-I` with metals listed in column`-II` and choose the correct option.
`{:("Column"-I,,"Column"-II),((a)"Self reduction method",,(p)"Aluminium from bauxite"),((b)"Carbon reduction method",,(q)"Mercury from cinnabar"),((c )"Electrolytic reduction method",,(r) "Zinc from zinc blende."),((d)"Cyanide process",,(s)"Silver from agentite"):}`

Options

A. `a-q,b-r,c-p,d-s`
B. `a-r,b-q,c-p,d-s`
C. `a-q,b-r,c-s,d-p`
D. `a-q,b-p,c-r,d-s`

Answer

1

Explanation

`(a)HgS+O_(2)overset("self reduction")rarrHg+SO_(2)`
`(b)2ZnS+3O_(2)overset(Delta)rarr 2ZnO+SO_(2)`
`ZnO+Coverset("carbon reduction")rarrZn+CO`
`(c )` `Al_(2)O_(3)(m)underset("reduction")overset("electrolyte")rarr Al(m)" "(d)Ag_(2)Sunderset("process")overset("cyanide")rarr Ag`
