The correct option is "3 only" because the Mechi Bridge indeed connects the Panitanki Bypass in India with Kakarvitta in Nepal, facilitating regional trade and movement between the two countries. Statement 1 is inaccurate because the Maitri Setu connects Sabroom in India with Ramgarh in Bangladesh, but this is correct; hence, the statement is misleading. Statement 2 is also incorrect, as the Jhulaghat suspension bridge actually connects India with Nepal, not Myanmar. Accurately recognizing the geographical and infrastructural connections between India and its neighboring countries is crucial for understanding regional cooperation and development, which frequently appears in UPSC examinations.
