According to API Std 936, responsibilities are clearly defined when it comes to conflicts in documents or drawings:
"Where conflicts exist in documents and/or drawings, resolution shall be by the owner."
- API Std 936, Section 4.2.1 Responsibilities
Therefore, Option B is correct. Inspectors may report or note discrepancies, but only the owner has the authority to officially resolve such conflicts.

API 936 requires a specific level of surface cleanliness before lining application:
"All surfaces to be lined shall be cleaned in accordance with SSPC-SP 7/NACE No. 4 (Brush-Off Blast Cleaning)."
- API Std 936, Section 5.3.2.1
This brush-off blast cleaning ensures adequate bonding without aggressive surface treatment.

Explanation:
Pallet
Batch
Testing Procedure
Sample
When a sample fails to meet the required specifications in accordance with API Std 936, any retesting must maintain strict consistency with the original conditions to ensure validity and comparability of results.
API 936 states:
"If a sample fails to meet any requirement, resampling shall be permitted. However, retesting shall be performed using specimens from the same batch, pallet, and sample as the original test. The same testing procedure must be used."
- API Std 936, Section 6.2.3
Explanation of Matching Terms:
Pallet: To ensure material consistency.
Batch: Revalidates results without introducing variability from a new production lot.
Testing Procedure: Methodology must not change to avoid skewed comparison.
Sample: Must be the original sample to confirm initial findings.
Therefore, all of these factors must remain the same. The only item in your provided list that is not required to match is "Inspection methods" - it is not part of the retesting condition clause.

Per API 936, linings that fall below the minimum thickness must be removed and replaced to maintain structural integrity:
"Areas below the minimum thickness shall be cut out and replaced."
- API Std 936, Section 8.2.1, Thickness Acceptance Criteria
Applying a skim coat (option B) is not an acceptable corrective action for substandard thickness.
