Noxious describes something that is which of the following?

• A. Detrimental to living beings
• B. Beneficial for health
• C. Pleasant to look at
• D. Not harmful

Answer: (A)

Noxious describes something that is harmful to living beings. It’s typically used for substances, fumes, or conditions that can injure health or cause poisoning—things that pose a risk or danger rather than being safe or beneficial. When you hear noxious, think of irritation, toxicity, or harm to the body or environment, not something pleasant or harmless.

So, the idea behind the correct option is that noxious means detrimental to health or well-being. It isn’t about being beneficial for health, it isn’t about appearance, and it isn’t about being not harmful. For example, noxious fumes can irritate the eyes and lungs, and noxious chemicals can be dangerous if touched or inhaled.
