Verified by Experts
The correct answer is:
D

Alcohols on dehydration can produce ether as well as alkene under different conditions.

Dehydration of alcohol proceeds through the formation of carbonium ion. The carbonium ion can lose a proton to form alkene. The carbonium ion may be attacked by a fresh molecule of alcohol and form an oxonium ion which can then lose a proton to form ether. Usually, secondary and tertiary alcohols form alkene.
