Concept:
Discourse Analysis is a qualitative research method that studies written, spoken or sign language in its social, cultural and political context. It examines how language is used to construct meanings, express power relations, shape identities and influence social and political behaviour.
Unlike traditional linguistic analysis, discourse analysis focuses not only on the language itself but also on the context in which communication takes place.
Step 1: Understand the meaning of Discourse Analysis.
Discourse Analysis investigates:
• Written texts such as books, newspapers and government documents.
• Spoken communication such as speeches, debates and interviews.
• Sign language and other symbolic forms of communication.
• The relationship between language, society and political institutions.
Thus,
\[
\boxed{
\text{Discourse Analysis studies language in its social and political context.}
}
\]
Step 2: Examine the given options.
• [(A)] Interpretation Analysis focuses on interpreting meanings but is not the established method for analysing language practices in social and political contexts.
• [(B)] Discourse Analysis studies written, spoken and sign language within their social, cultural and political settings.
• [(C)] Rational Choice Analysis explains decision-making based on individual preferences and utility maximisation rather than language.
• [(D)] Label Analysis is not a recognised research approach for studying language practices in social sciences.
Hence,
\[
\boxed{
\text{The correct answer is Discourse Analysis.}
}
\]
Therefore,
\[
\boxed{(B)\;\text{Discourse Analysis}}
\]
