Consider the following statements:
1. Supercharging increases the power output and increases the volumetric efficiency.
2. Supercharging is more suitable for S.I. engines than C.I. engines.
3. The limit of supercharging for an S.I. engine is set by knock while that for a C.I. engine is set by thermal loading.

Option (A)
2 and 3
Option (B)
1,2 and 3
1 and 3
1 and 2
Correct Option:
Question Solution:
