Which one of the following Union Territories of India is the smallest in terms of geographical area?

Lakshadweep is the smallest Union Territory of India in terms of both geographical area and population. It is an archipelago located in the Arabian Sea consisting of 36 islands, with a total land area of approximately 32 square kilometers [5]. In comparison, other Union Territories mentioned in the options have significantly larger areas: Chandigarh covers approximately 114 square kilometers, while the merged territory of Dadra and Nagar Haveli and Daman and Diu covers about 603 square kilometers [5]. Historically, Daman and Diu and Dadra and Nagar Haveli were separate entities but were merged into a single Union Territory in 2020 [3]. Despite these administrative changes, Lakshadweep remains the smallest administrative unit among all States and Union Territories in India.
