Which of the following two books have their roots in Foucauldian thoughts on sexuality?
A) Metahistory
B) Gender Trouble: Feminism and the Subversion of Identity
C) The Role of the Reader
D) Epistemology of the Closet
E) Sexual Politics
Choose the correct answer from the options given below:

The correct answer is B and D only.

To understand why these books are rooted in Foucauldian thoughts on sexuality, we can analyze the intellectual context and arguments of the works listed:
B) Gender Trouble: Feminism and the Subversion of Identity (1990) by Judith Butler: Butler's landmark text is heavily influenced by Michel Foucault's genealogical method and his critique of how power constructs identity. Butler draws on Foucault's ideas from The History of Sexuality to argue that gender and sex are not pre-existing biological essences, but are instead performatively produced and regulated through discourse and power structures.
D) Epistemology of the Closet (1990) by Eve Kosofsky Sedgwick: As a foundational text of queer theory, Sedgwick's work is deeply indebted to Foucault's historical analysis of sexuality. She examines how the homo/heterosexual definition has structured modern Western culture, built upon Foucault's insights into how sexuality became a central category of modern identity, knowledge, and social control.

Here is why the other options do not fit:
* A) Metahistory (1973) by Hayden White: This is a seminal work in historiography and literary theory that analyzes the narrative structures of historical writing, rather than sexuality.
* C) The Role of the Reader (1979) by Umberto Eco: This book focuses on semiotics, literary interpretation, and reader-response theory, exploring how readers interact with and generate meaning from texts.
* E) Sexual Politics (1970) by Kate Millett: Although a key feminist text analyzing power dynamics in gender relations, it predates Foucault's major published works on sexuality (such as The History of Sexuality: Volume 1, which was published in 1976) and draws from different theoretical frameworks like radical feminism.
