Correct Response: B. The live load is any load applied to a building that is not due to the weight of the building and its designed components. This typically includes loads attributable to outside forces such as weather, or to loads during use such as the weight of people and furniture. The weight of accumulated snow is a typical example of a live load. The weight of air-conditioning units (A), roof trusses (C), and structural members (D) are all examples of dead loads since they are due to the weight of the building and its designed components.
