A hotel wants to develop a green roof that is easy to maintain. The roof can only support about 20 pounds per square foot. Which is the best type of green roof for their space?(1 point)

The best type of green roof for this space would be an extensive green roof. Extensive green roofs are lightweight and low maintenance, suitable for roofs that can only support a limited amount of weight. They typically include shallow soil layers and drought-tolerant plants that require little watering and minimal maintenance.
