Explanation:

Sympatric species occur in the same geographical area. Since the two species of gray tree - frogs can exist in the same pond at the same time, they are sympatric. Allopatric species are geographically separated. Speciation in progress implies an ongoing process of becoming distinct species which isn't indicated here. Subspecies are within - species variants, but these are described as different species.

Answer:

They are sympatric species.
