Solution

The correct option is C
intramolecular dehydration

Ethanol, when heated with excess conc. $H_{2} S O_{4}$ at 443K undergoes intramolecular dehydration (i.e. removal of water from a molecule of ethanol) to give ethene.

$C H_{3} C H_{2} O H E t h a n o l c o n c . H_{2} S O_{4} - ------ \to 443 K C H_{2} = C H_{2} E t h e n e + H_{2} O$
