Solution

The correct option is B 1-b, 2-c, 3-d and 4-a
We observe a lot of energy conversions happening around us.
Bicycle converts muscular energy to mechanical energy, i.e., the energy we exert on pedals of a bicycle is converted into the motion of it. Engines used in automobiles convert the heat energy released due to the burning of fuel to mechanical energy (movement of the vehicle). Wind turbines convert wind energy to electrical energy. The solar panel converts solar energy (sun's energy) to electrical energy.
