The correct statement about the mass of a body is option 2: "It is the same everywhere."

This means that the mass of a body remains constant regardless of its location. Mass is an intrinsic property of an object and is not affected by gravity or the environment. For example, a 1kg mass on Earth would still have a mass of 1kg on the moon or in outer space.

Option 1: "It changes from one place to another" is incorrect. The mass of an object does not change based on its location or surroundings.

Option 3: "It depends on its shape" is also incorrect. The mass of an object is determined by the amount of matter it contains, regardless of its shape.

Option 4: "It does not depend on its temperature" is correct. The mass of an object remains constant even if its temperature changes. Temperature affects the kinetic energy of particles in the object, but it does not affect its mass.

In summary, option 2 accurately describes the nature of mass - it is the same everywhere, independent of location, shape, or temperature.
