Boundary Layer Thickness Vs Velocity - GATE ME '12

An incompressible fluid flows over a flat plate with zero pressure gradient. The boundary layer thickness is 1 mm at a location where the Reynolds number is 1000. If the velocity of the fluid alone is increased by a factor of 4, then the boundary layer thickness sat the same location, in mm will be A. 4 B. 2 C. 0.5 D. 0.25
