The Correct Option is B

Solution and Explanation

Concept: Different food items and natural substances contain characteristic acids responsible for their taste, sourness, and chemical behavior. Questions related to naturally occurring acids are common in chemistry and general science.

Step 1:
Analyze option (A) Tomato --- Oxalic Acid.
Tomatoes contain small amounts of oxalic acid, but they are not commonly identified with oxalic acid in standard matching questions. Hence, this pair is not considered the best correct match in this context.

Step 2:
Analyze option (B) Orange --- Citric Acid.
Oranges are citrus fruits and contain large amounts of citric acid. Citric acid gives oranges their characteristic sour taste. Therefore, this pair is correctly matched.

Step 3:
Analyze option (C) Vinegar --- Lactic Acid.
Vinegar mainly contains acetic acid, not lactic acid. Lactic acid is commonly found in curd and sour milk products. Hence, this pair is incorrect.

Step 4:
Analyze option (D) Tamarind --- Acetic Acid.
Tamarind mainly contains tartaric acid. Acetic acid is associated with vinegar. Therefore, this pair is also incorrect.

Step 5:
Determine the correct answer.
Among all the given options, the correctly matched pair is: \[ \boxed{\text{Orange --- Citric Acid}} \]
