Answer 2

`\qquad \qquad\huge \underline{\boxed{\sf Answer}}`

The Correct choice is 1

Because, in case of liquids the change is in volume, and only volumetric stress and strain is defined for that.

therefore, we use bulk modulus in that case. I hope that's sufficient to explain that phenomenon.

Have a great day !
