The answer would be D. This is because sulfur is on it's own, meaning one. while tri is a prefix for three so there are three oxygen atoms.

Element is a pure substance which is composed of atoms of similar elements. Example: Gold
Au

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. Example: water
