The melting points and boiling points for the pure substances W, X and Y are given. Melting point / $^\circ\text{C}$: $W = -114$, $X = 115$, $Y = -101$ Boiling point / $^\circ\text{C}$: $W = 78$, $X = 445$, $Y = -34$ The substances are chlorine, ethanol and sulfur. Which row matches W, X and Y?
- AW: chlorine, X: ethanol, Y: sulfur
- BW: ethanol, X: sulfur, Y: chlorine
- CW: sulfur, X: chlorine, Y: ethanol
- DW: sulfur, X: ethanol, Y: chlorine
