The order of reactivity of alcohols towards hydrogen halide is :
$b e n z y l > 3^{0} > 2^{0} > 1^{0}$
$3^{0} > b e n z y l > 2^{0} > 1^{0}$
$3^{0} > 2^{0} > 1^{0} > b e n z y l$
$3^{0} > 2^{0} > b e n z y l > 1^{0}$

Greater the stability of carbocation formed- greater is the reactivity- Benzyl carbocation is resonance stabilized-x2234-xA0-tertiary-gt-benzyl-gt-secondary-gt-primaryOption B is correct-

The order of reactivity of alcohols towards hydrogen halide is :benzyl>30>20>1030>benzyl>20>1030>20>10>benzyl30>20>benzyl>10

Greater the stability of carbocation formed, greater is the reactivity. Benzyl carbocation is resonance stabilized.∴ tertiary>benzyl>secondary>primaryOption B is correct.

The order of reactivity of alcohols towards hydrogen halide is :
$b e n z y l > 3^{0} > 2^{0} > 1^{0}$
$3^{0} > b e n z y l > 2^{0} > 1^{0}$
$3^{0} > 2^{0} > 1^{0} > b e n z y l$
$3^{0} > 2^{0} > b e n z y l > 1^{0}$

Greater the stability of carbocation formed, greater is the reactivity. Benzyl carbocation is resonance stabilized.

$∴ t e r t i a r y > b e n z y l > s e c o n d a r y > p r i m a r y$

Option B is correct.
