I tink the right answer should be option A.

Increasing the no Of passes do not change the velocity for the same flow rate.

Pressure drop is directly proportional to (n)^2.8.

Dear @Prakash. By increasing pass from 1 to 2, the velocity at the tube side also increase so it should be calculated in tube side pressure drop so the answer should be 6.96 times increasing.

P is directly proportional to the number of tube passes. So if it is changed from a single pass to two passes then P will be increased by 2 times.
