Exposure Routes describes how the substance enters the body and influences which organs are affected.

• A. Chemical Hazards
• B. Exposure Routes
• C. Flammable Liquid
• D. Health Hazard

Answer: (B)

Exposure Routes centers on how a chemical enters the body and which organs are impacted as a result. The route of entry—breathing it in, swallowing it, contact with the skin, or direct injection—determines which body systems are exposed first and how the substance is distributed, so different routes can affect different organs. For example, inhalation mainly targets the lungs and respiratory tract, ingestion affects the digestive organs and liver, and dermal exposure can impact the skin and may lead to systemic effects if absorbed. Given that description, the term Exposure Routes is the best fit because it directly links entry pathway to the organs that may be affected. Other terms describe general hazard properties or classes (like a hazard related to flammability or overall health risk) but do not specify how entry into the body influences which organs are affected.
