Section ____ outlines restriction on variation of records.

The correct answer is Section 45. This section typically outlines the restrictions on the variation or alteration of official records, particularly land records. This is a foundational concept designed to ensure the stability, integrity, and reliability of crucial documents, preventing arbitrary or unauthorized changes. It upholds the principle that once records are established, their modification must follow strict legal procedures.

• Section 39, Section 43, and Section 42 are incorrect. These sections generally deal with other aspects of land revenue law, such as the preparation of records, presumptions as to the truth of entries, or other procedural matters, but not specifically the restrictions on varying records.
