Which one of the following statements is correct?

The mass of an object is a measure of the quantity of matter it contains and is an intrinsic property that remains constant regardless of its location in the universe. In contrast, weight is the force exerted on an object due to gravity, defined by the formula W = m × g, where m is mass and g is the acceleration due to gravity.

Because the value of g varies depending on the location (for example, it is slightly higher at the poles than at the equator, and significantly different on other celestial bodies like the Moon), the weight of an object changes from place to place even though its mass remains the same. Therefore, statement A is correct.
