Solution

The correct option is A
the density of water is marked at the top of stem

It is because; the lightest density is that of water; so when hydrometer is immersed in water, most of its stem is under water. Thus, heavier densities are marked below the density of water, as lesser length of stem is immersed in the denser liquids
