Cross border oil pipeline inaugurated by P.M. Modi in September 2019 connects which of the following cities?

The correct answer is A) Motihari and Amlekhganj. The cross-border petroleum products pipeline runs about 69 km from Motihari in East Champaran, Bihar, to Amlekhganj in Nepal's Bara district, near Birgunj. It was built by Indian Oil with Nepal Oil Corporation and was inaugurated jointly by Prime Minister Modi and Nepal's PM K.P. Sharma Oli. Check the date: the inauguration is usually cited as May 2019, during Modi's Nepal visit, not September, so the month in the question is itself doubtful.

• B is wrong: Darbhanga is not on this line. Amlekhganj is correct, but its Indian end is Motihari.
• C is wrong: Kathmandu is Nepal's capital, but the pipeline terminates at Amlekhganj, not in the capital.
• D is wrong: Option A correctly names the two endpoints.

The core concept is cross-border energy infrastructure and India's Neighbourhood First policy. For Mains, it fits questions on energy connectivity with neighbours, the role of pipelines in fuel security for landlocked Nepal, and the India-Nepal energy relationship.

Trap: Aspirants choose Kathmandu because it is the obvious Nepali city, or pick Darbhanga because it is a larger Bihar city. Remember the line stops at Amlekhganj.
