The answer is B. They can be created by chemical reactions.

A compound is a substance
composed of two or more different atoms chemically bonded to one
another, for example, water (H₂O)
consists of 2 atoms of hydrogen (H) and 1 atom of oxygen (O), so it is the
compound. Water is created by chemical reaction:

2H₂ + O₂ → 2H₂O
