List-I
1. Intercooling
2. Isothermal compression
List-ll
A. No heat transfer during compression
B. Reduce low pressure compressor work
C. Heat rejection during compression
D. Reduce high pressure compressor work

1. C and B
2. A and B
3. C and A
4. A and D

Correct Option: A

Intercooling provides significant benefits to the brayton cycle gas turbine power plant through dereating the work of compression for the high pressure compressor.
Heat rejection taken place during isothermal compression.
