Correct Answer: Option A

Explanation

When C\(_2\)H\(_5\)OH (ethanol) reacts with excess acidified K\(_2\)Cr\(_2\)O\(_7\) (potassium dichromate), it produces ethanoic acid (CH\(_3\)COOH) as the main product; essentially, the alcohol is oxidized to a carboxylic acid by the strong oxidizing agent potassium dichromate.
