Text Solution
Verified by ExpertsThe correct answer is:
B
Reaction between alcohols and halogen acid follows 
mechanism. In 
Mechanism
carbocations are formed as intermediates.
Let us consider the formation of carbocations with the given three alcohols.
In this case, 
carbocation is formed. It is least stable. So, here 
mechanism is followed.
carbocation (more stable than 
carbocation)
carbocation (most stable)
