Solution

The correct option is A $C H_{3} - C H_{2} - C H_{3} | C | O H - C H_{2} C H_{3}$

The compound which can be easily dehydrated will form most stable carbocation after removal of $H_{2} O$ molecule.

Since stability of carbocation follows 3 degree> 2 degree> 1 degree,

so, compound $A$ is most easily dehydrated.

Option A is correct.
