Which Public Sector Enterprise has been conferred with the prestigious 'CSR Times Awards 2023' in 'Swachh Bharat' category for the 'Revival and operation of Municipal Solid Waste Management Plant, at Karsada, Varanasi'?

### Concept & Corporate Social Responsibility The 'CSR Times Awards' recognize outstanding achievements by corporate foundations, public sector enterprises, and NGOs in the field of Corporate Social Responsibility (CSR) in India. ### Step-by-Step Solution * The award in the 'Swachh Bharat' (Clean India) category was specifically bestowed for the "Revival and operation of Municipal Solid Waste Management Plant, at Karsada, Varanasi". * This project was successfully undertaken by NTPC (National Thermal Power Corporation). * The initiative focuses on scientific waste management and converting solid municipal waste into usable resources, aligning perfectly with national cleanliness goals. ### Exam Strategy & Shortcut When associating Varanasi and major infrastructure/waste management revivals backed by a PSU, NTPC has a very strong presence in Uttar Pradesh and actively funds significant urban projects there under its CSR mandate. ### Common Pitfall It is easy to assume that oil or civic-focused PSUs like ONGC or Indian Oil handled municipal waste projects, but NTPC explicitly took over the Karsada plant to convert waste to energy and compost. ### Final Answer Therefore, the correct answer is **NTPC**.
