Concept:
Different tribal and traditional societies practice different methods of acquiring spouses. Anthropologists classify these methods according to cultural customs and marriage practices.
Common methods include:
• Marriage by negotiation,
• Marriage by exchange,
• Marriage by probation,
• Marriage by elopement.
This question tests knowledge of ethnographic examples associated with these marriage customs.
Step 1: Matching marriage by negotiation.
Marriage by negotiation refers to marriage arranged through discussion and agreement between families.
Among the given groups, this form is associated with:
\[
\boxed{\text{Hos}}
\]
Therefore:
\[
A \rightarrow III
\]
Step 2: Matching marriage by exchange.
Marriage by exchange involves reciprocal exchange of brides between families.
This form is associated with:
\[
\boxed{\text{Melanesia}}
\]
Hence:
\[
B \rightarrow IV
\]
Step 3: Matching marriage by probation.
Marriage by probation allows a trial period before permanent marriage.
This custom is associated with:
\[
\boxed{\text{Kuki}}
\]
Thus:
\[
C \rightarrow II
\]
Step 4: Matching marriage by elopement.
Marriage by elopement involves partners running away and marrying without formal approval.
This custom is associated with:
\[
\boxed{\text{Oraons}}
\]
Therefore:
\[
D \rightarrow I
\]
Step 5: Writing the final matching combination.
The correct matches are:
\[
A \rightarrow III
\]
\[
B \rightarrow IV
\]
\[
C \rightarrow II
\]
\[
D \rightarrow I
\]
Thus, the correct answer becomes:
\[
\boxed{\text{(B) A-III, B-IV, C-II, D-I}}
\]
