Which of the following is NOT described as an exposure type in the material?

• A. Acute
• B. Chronic
• C. Transient
• D. Latent

Answer: (C)

Exposure types here are about how and when a hazard affects the body. Acute exposure means a short, often intense exposure that happens all at once or over a brief period. Chronic exposure refers to repeated or continuous exposure over a long time. Latent exposure describes a delay between the exposure and the onset of effects, so symptoms or damage show up after some time rather than immediately. Transient, while it can describe something short-lived in general language, isn’t listed as an exposure type in this material. The material groups exposure by duration and timing of effects—acute, chronic, and latent—so transient isn’t described within that framework.
