Solution

Correct Answer:

Bromoethane

Concentrated HBr converts alcohols to alkyl bromides by substituting the -OH group with Br. Therefore ethanol gives bromoethane as the main product. Ethene may form under strong dehydration conditions, but substitution with HBr is the expected major pathway here.
