I believe it is W (A) since W = mg and when cable breaks, weight of a person doesn't change, right?
yes but it asks about apparent weight... aka the Normal force..
your weight is still mg when you're falling through the air, but you feel effectively weightless..
...because there's no Normal force acting on you.
