What does aptly define minor literature, according to Giles Deleuze?

The correct option is Deterritorialisation of language.

According to the philosophers Gilles Deleuze and Félix Guattari in their influential work Kafka: Toward a Minor Literature (1975), a "minor literature" is not the literature of a minor language, but rather that which a minority constructs within a major language. They define minor literature through three essential characteristics:
1. The deterritorialisation of language.
2. The connection of the individual to a political immediacy.
3. The collective assemblage of enunciation.

The deterritorialisation of language refers to the way a minority writer uses a dominant, major language to express a different experience, effectively subverting, displacing, or destabilizing the language from its traditional cultural and territorial roots. For instance, they write about how Franz Kafka, a German-speaking Jew in Prague, used the dominant German language in a way that stripped it of its grand narratives, creating a unique, "deterritorialised" mode of expression that undermines the language's established authority from within.
