Step-by-step explanation:
The answer to this question is B) Only if specified. Mounting stationary equipment on legs that are at least 4 inches off the ground is typically done if specified in the equipment's instructions or if it is necessary for safety or stability reasons.
For example, certain types of machinery or heavy equipment may require specific leg heights to ensure proper functioning and stability. Additionally, elevating equipment off the ground can help prevent damage from moisture, dirt, or other environmental factors.
However, there may be situations where it is optional for convenience, especially if the equipment is portable and can be easily moved or adjusted as needed.
