Concept: Different stakeholders in disaster risk management have different responsibilities. Decision makers, businesses, the general public, and technical authorities contribute in different ways.
Step 1: Match decision makers.
Decision makers are responsible for policy decisions and strategic-level planning. Therefore, they are linked with strategic environmental assessment.
\[
A \rightarrow IV
\]
Step 2: Match business.
Businesses are connected with location planning and investment policies because they decide where to invest and how to reduce business risk.
\[
B \rightarrow III
\]
Step 3: Match general public.
For the general public, the main purpose is increasing awareness about disaster risk, preparedness, and safety.
\[
C \rightarrow I
\]
Step 4: Match technical staff of authorities.
Technical staff are responsible for applying and checking building codes, safety standards, and technical rules.
\[
D \rightarrow II
\]
Therefore, the correct matching is:
\[
A-IV,\ B-III,\ C-I,\ D-II
\]
