Solution Steps

Step 1: Identifying the type of alcohol

Dehydration of alcohols occurs most readily with tertiary alcohols, followed by secondary alcohols, and then primary alcohols. This is due to the stability of the carbocation intermediate formed during the reaction. More substituted carbocations are more stable.

Step 2: Classifying each alcohol
  • A is a primary alcohol.
  • B is a secondary alcohol.
  • C is a tertiary alcohol.
  • D is a primary alcohol.
  • E is a secondary alcohol.
Step 3: Determining the most readily dehydrating alcohol

Since tertiary alcohols dehydrate most readily, the answer is C.

Final Answer: The final answer is $\boxed{C}$
