Water is a liquid or fluid, it is not compressible perfectly, it can be compressed upto a minor extent. As given in FM text books that water is regarded as in compressible fluid.
But as we all know that the liquids may take any shape according to container in which it is poured. So there may be confusion regarding answer.

A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, it is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape.

Liquids are incompressible, can occupy shape of the container, and there is one more thing that properties of liquids may change based upon pressure and temperature conditions like by vapour pressure it could may cause vaporisation. So, the answer may be C. Because they do change their properties.

The answer is yes, You can compress water, or almost any material. However, it requires a great deal of pressure to accomplish a little compression. For that reason, liquids and solids are sometimes referred to as being incompressible. So B IS RIGHT ANSWER.

Because the particles in liquids are very close together (barely further apart than in solids) liquids do not easily compress, so their volume is fixed. Gases can also flow, so occupy the shape of their whole container. They do not have a fixed shape.

Liquids occupy definite volume but have no definite shape. This is because the inter-molecular force of attraction between the molecules in a liquid is less when compared to solids and the liquid molecules are loosely packed.

Liquid can compress then only we can have bulk elastic modulus but usually ignore and assume as liquid is incompressible and also water is incompressible but water only not liquid so given answer is correct.

Because the particles can move, liquids don't have a definite shape, and they can flow.
Because the particles are still packed close together, liquids can't easily be compressed and keep the same volume.

Fluids mean both gases and liquids.
But we are discussing liquids, which are incompressible and gases are compressible.
Liquids have no definite shape.
So the answer is cannot be compressed.
