Which of the following describes the properties of oxygen?

Colored, odorous, and flammable
Colored, tasteless, and supports combustion
Colourless, odourless, and tasteless
Odorous, colorful, and heavy

The correct answer is: Colourless, odourless, and tasteless

Oxygen is known to be a colorless, odorless, and tasteless gas at room temperature and pressure. This fundamental property means it does not impart any color, scent, or flavor, making it generally imperceptible to human senses in its natural gaseous state. Furthermore, while oxygen is essential for combustion, its properties in their pure form do not include any of the characteristics mentioned in the other options. Understanding these properties is critical, especially in environments where safe handling and awareness of substances are necessary, such as in industrial, laboratory, or medical contexts. This clarity helps ensure safe practices when working with gases and also informs individuals about oxygen's role in various chemical and biological processes.
