Answer

C

Explanation

`(CH_(3))_(3)C-OH +HCloverset(Anhy.ZnCl_(2)+HCl)rarr`
`(CH_(3))_(3)C-Cl +H_(2)O 3^(@)` reacts immediately
`(CH_(3))_(3)Ch-OH+HCl overset(Anhyd.ZnCI_(2)+HCl)rarr`
`(CH_(3))_(2)CH-Cl+H_(2)O 2^(@)` reacts after `5` min
`CH_(3)CH_(2)CH_(2)-OH +HCI overset(Anhyd.ZnCI_(2)+HCI)rarr`
`CH_(3)CH_(2)CH_(2)-CI +H_(2)O 1^(@)` reacts only on heating.
