This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Physiology
All are true about Reynold's number except 
Select and explain. 
A. Reynold's number calculates probability of turbulence, B. Reynold's number= ρDV / η, C. Reynold's number < 2000 indicates laminar blood flow, D. Reynold's number > 2500 indicates turbulent blood flow
D: Reynold's number > 2500 indicates turbulent blood flow
Answer: D: Reynold's number > 2500 indicates turbulent blood flow 
Explanation: Reynold's number= ρDV / η
ρ - Density of fluid
D - Diameter of vessel
V - Velocity of flow
η - Viscosity
Reynold's number ≤ 2000 indicates laminar blood flow
Reynold's number > 3000 indicates turbulent blood flow
