Acid catalysed dehydration of t-butanol is faster than that of n-butanol because

A

tertiary carbocation is more stable than primary carbocation

B

primary carbocation is more stable than tertiary carbocation

C

t-butanol has a higher boiling point

D

rearrangement takes place during dehydration of t-butanol.
