Relying on windows and building materials to capture incoming solar radiation without distributing that energy is called:
a: photoelectric heating
b: passive solar heating
c: active solar heating

Option (B)

Explanation:

Passive solar heating refers to the process in which the incoming solar radiations are being allowed to enter a room through the doors and windows, and are trapped within the walls of the rooms and building materials, which are later converted into electrical energy.

It is a very cheap and efficient method and causes no harm to the environment like the other energy sources such as radioactive energy and fossil fuel energy.

Thus, the correct answer is option (B).
