Why are liquids well suited for hydraulics? liquids have low densities. liquids are incompressible. liquids change volume easily. liquids have few molecules.

Liquid are incompressible.

Explanation:

Hydraulics is the branch of science and technology which deals with practical application of liquids in motion.

In hydraulics incompressible liquids are used. The use of incompressible liquids are used because due this property of liquid the pressure applied on the one end results in desired  pressure on an other end.

Hence, the correct option is liquid are incompressible.
