Assuming all tests are at the same altitude, vacuum - for the reasons given by the others saying d.

A body is heavier in vacuum because there is no buoyant force to lift it, thus act against gravity. In all other fluids there is a buoyant force

air.Bec. water give some upword force to a body.hydrogen is lighter then air & pressure has big role in weight of anybody.so less weight less pressure & all know that there is no weight in vaccum.

d
because no upward thrust is acted upon the body in vaccum

you are probably going to have to include a little more information. there are a lot of variables that go into a question like that.
