D is the answer.

The answer must be" D".
Because delivery pressure at the fourth stage means we should find P5, not P4. So P5 = 4^4.

Why 256 bar is wrong? Explain.

Thank you @Suresh.

The delivery of forth stage = p5.
p5 = 256.
p5 = 256.

There is clearly mentioned about four stage it means;
(P2/P1)*(P3*P2)*(P4*P3)*(P5*P4)= 4*4*4*4=256.
So, the right answer is D.
(P2/P1)*(P3*P2)*(P4*P3)*(P5*P4)= 4*4*4*4=256.
So, the right answer is D.

In multistage compressor the pressure in each stage follows geometric progression:
For 2nd stage: SQRT (1*16) = 4.
For fourth stage: 4*4*4 = 64.
For 2nd stage: SQRT (1*16) = 4.
For fourth stage: 4*4*4 = 64.
