    A is correct. B is incorrect.

    For A, weight = mass X acceleration due to gravity

    i.e. W = mg

    where g is the acceleration due to gravity (gravitationalfield strength), in which it can be treated as a constant.

    So, weight of an object at a particular place isproportional to its mass.

    For B, mass is a property of matter. That is it does not varyin different places. It should be the same at all places.

    Weight is a property of space. W = mg, The weight depends onthe magnitude of g, which can be varied. So it varies very slightly atdifferent places.

    you may ask,

    why the manitude of g can be varied? (statement2)
