What is the similarity between oxygen and ozone?

Answer and explanation

Correct answer: Both are allotropes of oxygen

Oxygen and ozone are allotropes because they are different structural forms of the same chemical element, oxygen. Ordinary oxygen exists mainly as O₂, a diatomic molecule, whereas ozone is O₃, a triatomic molecule with different molecular structure and properties. Ozone is more reactive and absorbs ultraviolet radiation in the upper atmosphere, while O₂ is the form commonly involved in respiration and combustion. Despite these differences, both contain only oxygen atoms, so option A is correct. They are not mixtures, metals, or salts. The governing concept is allotropy: one element can exist in more than one form in the same physical state.
