According to Stuart Hall, the concept of played a seminal role in Cultural Studies.

The correct option is Hegemony.

Stuart Hall, a foundational figure in British Cultural Studies and the Birmingham School, drew heavily on the works of Italian Marxist theorist Antonio Gramsci to develop his framework of cultural analysis. Gramsci's concept of hegemony describes how a dominant social class maintains power and control, not through direct physical force or coercion, but by securing the active consent of subordinate classes through cultural and ideological institutions (such as media, education, and religion). Stuart Hall adapted this concept to analyze how media texts encode dominant ideologies and how audiences decode them, positioning culture not as a static entity, but as a site of constant negotiation and struggle over meaning.

To understand why the other options are incorrect:
- Interpellation is a concept primarily associated with Louis Althusser, referring to the process by which ideology constitutes and addresses individual subjects.
- Dispositive (or dispositif) is a term developed by Michel Foucault to describe the heterogeneous ensemble of discourses, institutions, and administrative measures that maintain power relations.
- Society is a general sociological term rather than a specific seminal conceptual framework introduced or uniquely adapted by Stuart Hall to define the core methodologies of Cultural Studies.
