Answer #1

When ethanol is heated with conc. H₂SO₄ at about 413K ,intermolecular dehydration takes place to form diethyl ether.

But ethyl alcohol undergoes intramolecular dehydration when heated with conc. H₂SO₄ at about 443K to give ethylene.H,SO, 443 K > CH-CH, CH,CH,OH H,SO,

similarly in the question also the above rule will follow

so correct answer is C.
