Question
Read this paragraph about the benefits of a green roof. A green roof is created by adding soil and plants to a specially designed roof. Scientific research has shown that a green roof has many benefits compared with traditional roofs. Plants naturally absorb energy from the Sun and convert it into chemical energy that is stored in the bonds of sugars during photosynthesis. The soil materials also help insulate the building. In addition, a green roof helps control runoff as plant roots absorb rainwater. If local plants are used in the green roof, it may provide habitat for native species.

Explanation
The correct answer is option (c). The sentence supports the idea that green roofs can help reduce cooling costs by highlighting the insulation properties of the soil used in green roofs. Insulation is crucial for reducing the amount of heat that enters a building from the outside during hot weather, thus lowering the need for air conditioning and reducing cooling costs. The soil acts as a thermal barrier, moderating the temperature inside the building, making it more energy-efficient.
