Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Vinegar is a common household product used for cooking and preservation. It is derived from the fermentation of ethanol.
Step 2: Detailed Explanation:
Vinegar typically contains 5-8% of acetic acid by volume. Acetic acid's IUPAC name is ethanoic acid (CH\(_3\)COOH). Other acids like citric acid (in citrus fruits) and oxalic acid (in tomatoes, spinach) are not the primary component of vinegar.
Step 3: Final Answer:
Vinegar is a dilute solution of ethanoic acid, option (A).
