Explanation:

An element is a pure substance consisting of only one type of atom. Hydrogen (H) is an element with atomic symbol H. Carbon (C) is an element with atomic symbol C. Oxygen (O) is an element with atomic symbol O. Sugar ($\ce{C6H12O6}$) is a compound (made of multiple elements), and water ($\ce{H2O}$) is also a compound (made of hydrogen and oxygen). So the three elements are Hydrogen, Carbon, and Oxygen.

Answer:

Hydrogen (H), Carbon (C), Oxygen (O)
