Assertion (A): Stagnation pressure is conserved across any adiabatic process.
Reason (R): Stagnation pressure is conserved only where the entropy does not rise.
Select the correct answer from the options below.
Answer: D
The assertion is false and the reason is true. Adiabatic is not enough: the process must also be reversible. A shock wave is the standard counter-example, being adiabatic yet strongly irreversible, and it destroys stagnation pressure while leaving stagnation temperature untouched.
