d
Explanation:
Condensation nuclei are important because they form the basic building blocks of clouds. The condensation nuclei are tiny particles on which water vapor molecules form to create the most basic elements of clouds.
Later, other water molecules continue grouping around the original condensation nuclei and get larger to form raindrops.
D. They do not produce electricity.
Passive solar heating is a technique where the sun's energy
is used for heating spaces. It does not generate electricity but can save substantial
electricity by making use of thermal mass. Materials that have a high density
such as concrete and bricks absorb and store electricity. Along with operable windows
and thermal chimneys, thermal mass is being
utilized to take advantage of sun exposure.
