Question

a(n) _______ exposure is a short term or brief exposure that may create an immediate health hazard.
acute
chronic
emergency
short

Explanation:

To solve this, we analyze the definitions: "Acute" exposure is defined as short - term or brief exposure that can cause immediate health hazards. "Chronic" exposure is long - term. "Emergency" is about a situation, not the duration of exposure. "Short" is not the technical term used in this context for this type of exposure. So the correct term is "Acute".

Answer:

A. Acute
