Francis turbine is used when the available head of water is 25m to 250m.
Here, the head is 150m.
60 to 300 rpm for Francis turbine.
So, I think the answer will be Francis turbine (D).

Given answer is correct. While calculating specific speed we always put power in kw.

@Ajaypal
The range of specific speed is wrong.
Range for sp. Speed.
For pelton or impulse - 1-10.
Francis-10-100.
Kaplan- more than 100 rpm.
Correct ans is francis turbine 22.13 lies between 10-100.
