The effect of increasing the stirrer speed in an unbaffled stirred tank reactor is that

A. a small increase in stirrer speed will cause the liquid to enter the turbulent flow regime
B. as the stirrer speed increases, the liquid will continue to circulate and then become turbulent
C. as the stirrer speed increases, the liquid will continue to circulate. Eventually a vortex will form.
D. A vortex will form at low stirrer speeds. As the stirrer speed increases the liquid will start to circulate
