Explanation:
Answer: D.two or more elements are chemically bonded
Explanation:
Compound is a pure substance which is made from atoms of different elements chemically combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. They have different properties as compared to their constituents. Example: water 

Element is a pure substance which is composed of atoms of similar elements.It can not be decomposed into simpler constituents using chemical reactions.Example: Copper 
Thus every compound is made up of two or more elements chemically bonded.
