Given below are two statements:
Statement I: Acute health effects are caused due to prolonged exposure to a chemical.
Statement II: Chronic health effects occur when an individual is exposed for a very short period.
In the light of the above statements, choose the correct answer from the options given below:
Answer: B. Both Statement I and Statement II are false — CONCEPTAcute and chronic health effects are classified mainly by the time course of exposure and response, not simply by how severe an effect sounds. Acute…

Both Statement I and Statement II are false
- C.
Statement I is true but Statement II is false
- D.
Statement I is false but Statement II is true
Show answer & explanation
Correct answer: B
CONCEPT
Acute and chronic health effects are classified mainly by the time course of exposure and response, not simply by how severe an effect sounds.
Acute effects generally follow a single or brief exposure and appear rapidly; chronic effects generally arise after repeated or prolonged exposure and may develop gradually.
APPLICATION
Statement I links acute effects with prolonged chemical exposure. Prolonged or repeated exposure belongs to the chronic time course, so Statement I is false.
Statement II links chronic effects with a very short exposure. A short exposure is associated with the acute time course, so Statement II is false.
CONTRAST
Both true: reverses the standard time-course association for both terms.
Both false: preserves the short-term acute and long-term chronic distinction.
Statement I true, Statement II false: misclassifies prolonged exposure as acute.
Statement I false, Statement II true: misclassifies short exposure as chronic.
CROSS-CHECK
Replacing the labels with their time courses gives brief exposure → acute and prolonged exposure → chronic. Neither statement follows this mapping.
RESULT
Therefore, both Statement I and Statement II are false.
