Why 256 bar is wrong? Explain.

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

P2/p1 = p3/p2 = p4/p3 By using this we will get the answer.

The delivery pressure at the fourth stage means p5.
So p1 is 1.
P2 is 4.
P3 is 16.
P4 is 64.
P5 is 256.
So option D. 256 should be correct.

@All.
The pressure mentioned in the question are the Delivery pressure. If we assume P2 as 1 bar and P4 as 16 bar, then only P5 comes as 64 bar.
