The group which should be chosen is Birds because of the homologous structures, the trait shared only with bats is derived.
These are the physical structures which common ancestors share but however have different functions.
In the case of a Bird which has a common homologous with the organism depicts that the traits shared with bat is derived because it is analogous and aren't similar in structure thereby making it the correct choice.

The correct question is:
A scientist finds a new organism that may be either a bird or a bat, but it is not clear which group it belongs to. He is pretty sure that the organism has analogous structures with bats and homologous structures with birds, as suggested by genomic data. The organism has one trait that is shared with bats but not birds which group should he choose for the new organism and why?
