Solution

The correct option is C constant
An incompressible fluid is defined as one whose density does not change on applying pressure, it's and ideal liquid and does not exist in real life.
Whereas incompressible flow means when the density of small elements in a flowing liquid does not change of applying pressure. The independent density of each small element may vary but also constant.
