To compare we can quickly say:

Ethene can be made by an elimination reaction. Therefore A is incorrect.

Ethanal and Ethanoic Acid can be formed by the oxidation of Ethanol. Therefore B and C are incorrect.

Ethoxyethane can be formed by the dehydration of Ethannol. Therefore D is also incorrect.

Bromoethane can only be formed by a simple substitution reaction of Ethanol, which makes E our answer.

It’s a tough question, isn’t it?:face_with_spiral_eyes::sob:

Can someone please explains why the reaction between ethanol and O is an oxidation reaction? Because the atoms in ethanol have covalent bonds and the atoms are neutral and not charged.

Oh! Thank you very much🙏
