The correct choice is to extend the mast horizontally when it is near the ground. This position minimizes the risk of the mast coming into contact with nearby obstacles, such as trees or buildings, which can lead to damage to the mast or equipment. A horizontal position also increases safety for personnel working in the area, as it reduces the height of the mast and makes it less likely to interfere with overhead power lines or other hazards.

Extending the mast vertically when it is close to the ground can be dangerous, as it increases the risk of tipping over or striking nearby objects. Similarly, a diagonal position may still present hazards due to the mast's height and angle, making it less stable and potentially leading to accidents. Keeping the mast below ground level is impractical for operational purposes, as it would not allow for effective communication or signal transmission. Therefore, the horizontal position is the best choice for safety and functionality when the mast is near the ground.
