\nThe correct answer is D. Wallace’s Line is a faunal boundary line that separates the ecozones of Asia and Wallacea, a transitional zone between Asia and Australia. It effectively distinguishes or separates the flora and fauna between South-East Asia and Australasia.
\n<\/section>\n
\n– Wallace’s Line was proposed by Alfred Russel Wallace based on his observations of dramatic differences in animal distribution across the Malay Archipelago.
\n– West of the line, species are largely of Asian origin (e.g., tigers, rhinos, monkeys).
\n– East of the line, species are largely of Australian origin (e.g., marsupials, cockatoos).
\n– The line runs through Indonesia, between Borneo and Sulawesi, and between Bali and Lombok.
\n<\/section>\n
\nWallace’s Line is thought to reflect a deep ocean trench that acted as a barrier to migration even during lower sea levels in glacial periods. This prevented many species from crossing between the Asian and Australian continental shelves.
