Which of the following statements is most closely associated with analytical procedure applied at substantive stage?

Answer: Option B

Analytical procedures used at the substantive stage are specifically intended to detect potential material misstatements in the financial statements. During this stage, auditors compare recorded figures with expected values based on analytical relationships. Any unusual or unexpected variations indicate areas where misstatements may exist. Hence, Option B correctly reflects the primary purpose of analytical procedures at the substantive testing level.

Why the Other Options Are Incorrect:

Option A: "It helps to study relationship among balance sheet accounts"
This reflects the purpose of analytical procedures during the planning stage, where auditors study relationships to understand the entity and identify risky areas. It does not specifically relate to detecting misstatements during substantive testing.

Option C: "It helps to identify possible oversights"
This is associated with the overall review stage at the end of the audit, where auditors use analytical procedures to ensure the financial statements are consistent and reasonable. It is not the main objective of substantive analytical procedures.

Option D: "It helps to accumulate evidence supporting the validity of a specific account balance"
This describes tests of details, not analytical procedures. Analytical procedures examine trends and relationships, whereas validating a specific account balance requires detailed audit techniques such as vouching, verification, or confirmations.

Final Conclusion:
Only Option B correctly states the primary purpose of analytical procedures at the substantive stage—identifying material misstatements.
