The reason for supercharging in any engine is to

A Increase efficiency
B Increase power
C Reduce weight and bulk for a given output
D Effect fuel economy

Correct Answer: Reduce weight and bulk for a given output

The reason for supercharging in any engine is to Reduce weight and bulk for a given output-A supercharger is an air compressor that increases the pressure or density of air supplied to an internal combustion engine. This gives each intake cycle of the engine more oxygen, letting it burn more fuel and do more work, thus increasing power.
