<reasoning>

Analyze the Wallace Line boundary

The deep-water strait separating the Indonesian islands of Bali and Lombok marks the Wallace Line, a major biogeographical boundary.

Identify the ecological division

This boundary separates two distinct global ecozones: the Indomalayan (Oriental) ecozone to the west (including Bali) and the Australasian ecozone to the east (including Lombok).

Evaluate the options

The difference in vegetation and wildlife exists because the islands belong to different ecozones, despite their close geographic proximity.
