No, C is correct answer. In reaction turbine, when steam flows through the (fixed blades) - pressure decreases while velocity increases, but in case of (Moving blades) pressure and velocity both decreases.

No, C is the correct answer because of velocity decrease in the moving blade.
The blade of moving blade is not symmetric as in impulse turbine it is in aerofoil type, so when steam pass through moving blade c/s became slightly decreases so by giving momentum of steam the velocity decreases and also pressure will decreases.
