Show answer

Answer: (D) None

All three are wrong.

Statement 1: The East-West Corridor connects Silchar (Assam) to Porbandar (Gujarat), not Rajkot.

Statement 2: The India-Myanmar-Thailand Trilateral Highway connects Moreh (India) to Mae Sot (Thailand) via Myanmar, not directly to Ho Chi Minh City.

Statement 3: The BCIM Corridor runs from Kunming (China) through Myanmar and Bangladesh to Kolkata (India), not Lucknow.

Answer is (d).

Why this was asked

India has multiple connectivity projects with neighboring countries as part of Act East Policy and regional integration efforts.

UPSC tests exact endpoints and routes of major connectivity corridors, not just their existence - students often confuse similar-sounding projects or mix up terminal cities.

The question checks whether students can distinguish between domestic highway projects like Golden Quadrilateral versus international connectivity corridors like BCIM and Trilateral Highway.
