Correct Answer: Option C
Explanation

The dehydration of ethanol is a chemical reaction that produces ethene and water from ethanol: 

The chemical equation for the dehydration of ethanol is:

CH\(_3\)CH\(_2\)OH  +  H\(_2\)SO\(_4\) →  CH\(_2\)=CH\(_2\) + H\(_2\)O

The reaction is performed by heating ethanol with concentrated sulfuric acid at around 170°C. Sulfuric acid is a dehydrating agent, meaning it absorbs water.

There is an explanation video available below.
