Solution

The correct option is A $C_{2} H_{5} H S O_{4}$ , $C_{2} H_{5} O C_{2} H_{5}$ , $C_{2} H_{4}$
At 383K, sulfuric acid reacts with ethanol to form ethyl hydrogen sullfate and water.
At 431K, in presence of sufluric acid, 2 molecules of ethanol gives one molecule of diethyl ether. Water is eliminated in the process.
At 443K, dehydration of ethanol in presence of sulfuric acid gives ethene.
