Explanation:

The elements in the "Periodic Table" are arranged in groups according to their characteristics.

X- Selenium

Z- Xenon

W- Magnesium

Y- Barium

A. X has a lower boiling point than Y. Selenium's boiling point is 685 while Barium's boiling point is 1,140. This makes choice A incorrect.

B. Y is a metal while Z is a non-metal. This makes choice B incorrect.

C. Both W and X are non-metals. Both are in the Alkaline Earth group. This makes choice C correct.

D. Z has different chemical properties than W because they don't belong in the same group. Z is a noble gas while W is an Alkaline Earth Metal.
