The diagram illustrates a U-tube manometer that contains three liquids: mercury, liquid X and liquid Y. Neither liquid X nor liquid Y is miscible with mercury. Which row compares the pressure applied by liquid X and by liquid Y to the mercury, and the density of liquid X and the density of liquid Y?
- Apressure of X is greater than Y; density of X is greater than Y
- Bpressure of Y is greater than X; density of Y is greater than X
- Cpressure of X and of Y is the same; density of X is greater than Y
- Dpressure of X and of Y is the same; density of Y is greater than X
