The correct option is
B One
Option A: 'One' refers to a single unit. Here it refers to 'Bali' as one from the 26 Provinces of the Republic of Indonesia.
Hence option A is correct.
Option B: 'Either' presents a choice between two things or people. The given sentence does not present a choice.
Option C: 'Any' refers to an unspecified number or quantity. But Bali is one single island, and cannot be modified as 'any'.
Option D: 'Those' demonstrates a plural noun that is at a distance. But here, Bali is singular.
Hence options B, C and D are incorrect.
