• C. Tartaric Acid
• D. Oxalic Acid

Hint:

Remember common natural acids:

• Vinegar --- Acetic Acid
• Citrus fruits --- Citric Acid
• Tamarind --- Tartaric Acid

Answer 1

The Correct Option is B

Concept: Different naturally occurring substances contain different organic acids responsible for their taste and chemical properties. Vinegar is a commonly used acidic liquid in cooking and food preservation.

Step 1: Understand the composition of vinegar.
Vinegar mainly contains dilute acetic acid dissolved in water. Chemically: \[ \text{Acetic Acid} = CH_3COOH \] It gives vinegar its characteristic sour taste and pungent smell.

Step 2: Analyze option (A) Citric Acid.
Citric acid is mainly found in citrus fruits such as:

• Lemon
• Orange
• Mosambi

Therefore, this option is incorrect.

Step 3: Analyze option (B) Acetic Acid.
Acetic acid is the principal acid present in vinegar. Hence, this option is correct.

Step 4: Analyze option (C) Tartaric Acid.
Tartaric acid is commonly found in tamarind and grapes. Thus, this option is incorrect.

Step 5: Analyze option (D) Oxalic Acid.
Oxalic acid is found in spinach and tomato. Therefore, this option is also incorrect.

Step 6: Write the final conclusion.
Thus, the acid commonly found in vinegar is: \[ \boxed{\text{Acetic Acid}} \]
