None of the statements are correct. The East-West Corridor under the Golden Quadrilateral Project connects Silchar in Assam to Porbandar in Gujarat, not Dibrugarh and Surat. The Trilateral Highway indeed connects India to Thailand through Myanmar, starting from Moreh, but it doesn't directly connect to Chiang Mai; it extends further into Thailand. Lastly, the Bangladesh-China-India-Myanmar Economic Corridor (BCIM) is intended to connect Kunming in China with Kolkata in India, not Varanasi. Understanding the specifics of these infrastructure projects is crucial in UPSC exams, as they reflect India's regional connectivity strategies and geopolitical relationships in South and Southeast Asia.
