90 million years ago (mya), a single bat species existed on a landmass. That species served as a common ancestor of the four bat
species now found in the region. The image below shows how the landmasses have changed over time and the current distribution
of the bat species

relationship of these species?

Species 2 shares a more recent common ancestor with species X than with species w.
B. Species W shares a more recent common ancestor with species Y than with species X
C. Species X shares a more recent common ancestor with species Z than with species W
D. Species Y shares a more recent common ancestor with species W than with species Z
