The correct answer is (a). Kinetic energy is the energy of motion. Wind is caused by the uneven heating of the Earth’s surface by the sun. The sun heats the Earth’s surface unevenly, causing the air to rise in some places and sink in others. This creates an air current, which we call wind. The wind blows the blades of a wind turbine, which turn a generator to produce electricity.
(b) Potential energy is stored energy. It is the energy that an object has due to its position or state. For example, a ball held above the ground has potential energy because it could fall and hit the ground.
(c) Solar energy is energy from the sun. It can be converted into electricity using solar panels.
(d) Radiant energy is energy that travels in waves. It can be heat energy, light energy, or other types of energy.
