Explanations:The question pertains to the reading habits of Iswaran, a character from Tamil literature. Understanding the cultural context and the literary preferences of Tamil Nadu is crucial to answering this question correctly. Tamil Nadu, a state in southern India, has a rich literary tradition, and the Tamil language is central to its cultural identity. The genre of thrillers is popular among readers in Tamil Nadu, reflecting the region's interest in suspenseful and engaging narratives.
Iswaran, as a character from Tamil literature, would naturally be associated with reading materials that are both linguistically and thematically relevant to the region. Tamil is the primary language spoken in Tamil Nadu, and it is the language in which most of the literature is produced. Therefore, it is logical to assume that Iswaran would read books in Tamil.
Among the genres, thrillers are particularly popular in Tamil Nadu. Thriller novels often involve suspense, mystery, and action, which can captivate readers and keep them engaged. This genre aligns well with the cultural and literary tastes of the region, making it a plausible choice for Iswaran's reading material.
Other options such as Sanskrit, Urdu, and Punjabi are not the primary languages of Tamil Nadu, and the genres of biographies, romantic novels, and comic books do not align as closely with the typical reading preferences of the region. Therefore, the correct answer is that Iswaran usually reads Tamil thrillers.
