Solution

The correct option is C
Ethene

When ethanol ( ${CH}_{3} {CH}_{2} OH$ ) is reacted with concentrated sulphuric acid ( $H_{2} {SO}_{4}$ ), dehydration reaction takes place means water ( $H_{2} O$ ) molecular is produced.
$H_{2} {SO}_{4}$ act as a dehydrating agent.
Ethene ( ${CH}_{2} = {CH}_{2}$ ) is formed as the final product.
The chemical reaction takes place as:
${CH}_{3} - {CH}_{2} - OH \overset{Hot conc . H_{2} {SO}_{4}}{\to} {CH}_{2} = {CH}_{2} + H_{2} O Ethanol Ethene water$

Hence, option C is correct answer.
