a. Trees shade buildings which reduces the use of energy derived from fossil fuel.

Trees shade buildings and provides thermal insulation in winters and provide shade against excess heat from the sun in summers. The fossil fuels are required to produce energy in the form of electricity, which is utilized as a source of energy for maintaining household temperature like heating from heater or other appliances or cooling from air conditioners which requires fossil fuels like natural gas, coal and petroleum.
