Concept:
Different social, economic, and health indicators are associated with specific areas of measurement.
• Global Hunger Index reflects nutritional status.
• Gross Domestic Product (GDP) is related to national income and economic output.
• Maternal Mortality Ratio indicates female reproductive health conditions.
• Opinions represent views held by people regarding an issue or dispute.
Step 1: Match Global Hunger Index.
Global Hunger Index measures hunger and nutritional condition in populations.
Hence,
\[
A \rightarrow IV
\]
Step 2: Match Gross Domestic Product.
GDP measures the economic output and national income of a country.
Hence,
\[
B \rightarrow I
\]
Step 3: Match Maternal Mortality Ratio.
Maternal Mortality Ratio reflects the condition of female reproductive health and maternal healthcare.
Hence,
\[
C \rightarrow II
\]
Step 4: Match Opinions.
Opinions are views or beliefs held by individuals on a disputed or discussed matter.
Hence,
\[
D \rightarrow III
\]
Step 5: Select the correct option.
Thus, the correct matching is:
\[
A-IV,\; B-I,\; C-II,\; D-III
\]
Therefore, the correct answer is:
\[
\boxed{(B)\ A-IV,\; B-I,\; C-II,\; D-III}
\]
