The given statements refer to important connectivity projects involving India. However, all three options are inaccurate.

1. The East-West Corridor, part of the Golden Quadrilateral Project, connects Silchar in Assam and Porbandar in Gujarat, not Dibrugarh and Surat.

2. The Trilateral Highway does connect Moreh in India and Mae Sot in Thailand via Myanmar, but it does not extend up to Chiang Mai in Thailand.

3. The Bangladesh-China-India-Myanmar (BCIM) Economic Corridor aims to link Kolkata with Kunming, China. It doesn`t connect Varanasi in Uttar Pradesh with Kunming in China.

Therefore, none of the given statements are correct, which makes Option 4, "None," the correct answer.

These inaccuracies highlight the importance of careful study and understanding of the geographical and geopolitical aspects linked with India`s connectivity projects.
