What are the minimum diameter and length of the hardwood post used to mark the disputed area?

• A. 10 cm in diameter and 2 meters in length
• B. 5 cm in diameter and 1 meter in length
• C. 20 cm in diameter and 3 meters in length
• D. 15 cm in diameter and 2.5 meters in length

Answer: (A)

The main idea is choosing a boundary marker that is sturdy enough to endure the elements and tampering while remaining practical to install and read. A hardwood post with a diameter of about 10 cm provides sufficient strength to resist bending and breakage in typical field conditions, ensuring the marker stays in place over time. A length of about 2 meters gives enough depth to stabilize the post when driven into the ground and leaves enough portion above ground for clear marking and visibility. The other options either use too small a diameter and risk damage, or are unnecessarily large or long, making installation and handling impractical. Therefore, 10 cm in diameter and 2 meters in length best meet the needs for a reliable disputed-area marker.
