The definition of 'boundary mark' is fundamental in land demarcation and dispute resolution. A comprehensive understanding ensures that all forms of physical indicators used to define property lines are legally recognized. The term 'boundary mark' legally encompasses any mark, whether natural or artificial, that serves to delineate the limits of a piece of land. This broad definition ensures clarity and prevents ambiguity in land surveys and ownership.

• Any mark natural or artificial (Correct): This is the comprehensive legal definition, including both natural features (e.g., rivers, hills) and man-made structures (e.g., pillars, fences).
• Only natural boundaries (Incorrect): This is too restrictive, as artificial marks are commonly used and legally recognized.
• Water bodies (Incorrect): While water bodies can be natural boundaries, this option is not exhaustive and excludes artificial marks.
• Khasra numbers (Incorrect): Khasra numbers are survey plot numbers, not physical boundary marks themselves, though they refer to plots defined by boundaries.
