Is A Turbine Pump Considered A Centrifugal Pump Or A Positive Displacement Pump? Explain?

Yes, a turbine pump is centrifugal pump because the amount of fluid that is displaced depends on the resistance of the existing piping system (given a constant speed).
A positive displacement pump is going to have a fixed volumetric displacement for a given speed.
Really what I think you mean when you say “turbine pump” is a turbine driven centrifugal pump. In other words a high energy pump, like a boiler feed water pump.

A turbine pump usually consists of multiple stages, or bowls. They use end suction impellers, making it a centrifugal pump. A positive displacement pump normally uses gears or vanes.

why don’t you look it up yourself? That’s a question right out of your homework assignment.
