A deconstructive reading of a text shows that:

(a) a text is to be read always in a context
(b) there is nothing except the text
(c) a text may betray itself
(d) a text may possess an ascertainable meaning
(e) there is an endless postponement of meaning

Correct option is C

Explanation:
There is nothing except the text: Deconstruction, a philosophical approach developed by Jacques Derrida, suggests that meaning arises solely from the text itself. It focuses on the idea that the text is self-contained, and interpretation arises from within rather than being influenced by an external context.
A text may betray itself: Deconstruction emphasizes that texts may contradict themselves. The meaning of a text can be unstable and self-subverting, making it possible for the text to "betray" or undermine its intended meaning.
There is an endless postponement of meaning: One of the key ideas in deconstruction is the concept of "différance," which refers to the endless deferral of meaning. Meaning is never fully realized, and interpretation is always in flux, perpetually postponed.

Deconstruction: A form of critical theory developed by Jacques Derrida, deconstruction argues that all texts have multiple interpretations, and that meanings are not fixed but constantly shifting.
Différance: Derrida introduced the term différance to suggest that meaning is never fully present in a text and that it is constantly deferred through language. Meaning is always contingent on further interpretation, which makes complete closure or resolution impossible.
Self-Betrayal of Text: The idea that a text may betray itself reflects deconstruction’s belief that texts are inherently unstable. This self-contradiction reveals the text's inner tensions and the impossibility of a singular, fixed meaning.
Deconstruction critiques the idea that a text can be fully understood within a fixed context. While context influences meaning, deconstruction focuses on how a text’s meaning is constantly altered by language and its internal contradictions, thus destabilizing a fixed interpretation.
Deconstruction is often applied to literary, philosophical, and legal texts. The theory undermines traditional structuralist approaches and reveals that any given text can support a multiplicity of interpretations. It encourages readers to explore the "gaps" and contradictions within texts.
The term “endless postponement of meaning” (différance) challenges the traditional idea of a final, determinate meaning that can be extracted from a text. In deconstruction, meanings are contingent and always evolving.
