Which term describes something poisonous or dangerous to humans by swallowing or inhalation?

• A. Toxic
• B. Sidelite
• C. Solvant
• D. Ultraviolet Light

Answer: (A)

Toxic is the term that describes a substance poisonous or dangerous to humans when it is swallowed or inhaled. It captures the idea that certain materials can cause harm through ingestion or breathing in their vapors, dust, or aerosols, and the level of danger depends on factors like dose and exposure duration. This is the language used in safety contexts to warn about substances that pose poisoning risks.

The other options don’t fit this specific idea. A sidelite is simply a window panel and has no inherent meaning related to chemical toxicity. A solvent describes a substance used to dissolve other materials; while some solvents can be hazardous, the word itself doesn’t specifically denote poison by swallowing or inhalation. Ultraviolet light is a type of radiation that can harm skin or eyes with exposure, not a poison that acts through ingestion or inhalation.
