Show answer & explanation
Correct answer: A
Concept
Environmental risk assessment is an umbrella process that integrates hazard identification, dose–response assessment, exposure assessment, and risk characterization.
Frameworks may present the middle analyses in different orders; this PYQ must therefore be interpreted against its official examination key rather than as a universal five-stage scientific standard.
Application
Read D as Hazard Identification.
The official sequence then places A (Exposure Assessment) and B (Dose–Response Assessment).
E is Risk Characterization, which integrates the component evidence.
C is the question’s label for the concluding overall Risk Assessment.
Thus the official-key sequence is D, A, B, E, C.
Cross-check and contrast
The NTA final answer key lists Correct Opt_ID 1 for the source question; that maps to the stored value D, A, B, E, C.
D, A, B, C, E swaps the final two labels relative to the official key.
C, E, D, B, A starts with the overall-assessment label rather than the official key’s opening label.
E, C, B, A, D follows a different order throughout and ends with Hazard Identification.
