A. Paddle and anchor mixers operate at low speed - correct.
B. Propeller mixers are not for high viscosity - incorrect.
C. Turbine mixers operate at high speed - correct.
D. Propeller mixers blend low viscosity liquids - correct.
Thus, A, C, and D are correct.
Step 4: Final Answer:
The correct statements are (A), (C), and (D).
Hence, the correct option is (D).
