The passage links the narrator's birthplace (Pandari, about 30 km from Motihari) with Orwell's birthplace (Motihari), and it is this shared Motihari connection in Bihar that inspires the narrator. Among the options, option 1 is the intended match.
Note: Strictly speaking, the narrator was born in Pandari, not Motihari, so option 1 is a close approximation intended by the paper.
