Answer

Brief Explanations:

Acute toxicity is defined as adverse effects from a single or short-term high exposure to a toxic substance, while chronic toxicity develops from repeated, long-term low-level exposures. The other options are incorrect: acute toxicity does not always cause death, chronic toxicity can also be fatal; the third option reverses the exposure requirements; LD₅₀ values relate to dose, not the acute/chronic classification itself.

Answer:

B. Acute toxicity can occur with a single exposure. Chronic toxicity requires repeated exposures.
