Solution

The correct option is B False
The dehydration of ethanol to give ethene not ethane.
Ethanol is heated with an excess of concentrated sulphuric acid (act as a catalyst) at a temperature of 170C. The gases produced are passed through sodium hydroxide solution to remove the carbon dioxide and sulphur dioxide produced from side reactions.The ethene is collected over water.
$C H_{3} - C H_{2} - O H$ $H_{2} S O_{4} \to$ $C H_{2} = C H_{2}$ + $H_{2} O$
Option B is correct.
