What is the Reynolds number and what does it indicate?

I - The Reynolds number is a dimensionless parameter that classifies the flow regime of a fluid in a pipe.
II - The Reynolds number is defined as the ratio of the inertial forces to the viscous forces in the fluid.
III - The Reynolds number is used to determine whether the flow is laminar, turbulent, or in transition.
IV - The Reynolds number is affected by the fluid density, velocity, and viscosity, as well as the pipe diameter.
a) I, II, III, and IV are correct.
b) I, II, and III are correct.
c) II, III, and IV are correct.
d) Only III is correct.
