Final answer:
The habitat most likely to harbor recently diverged species would be one with a burst of speciation and a large number of endemic species, along with genetic diversity that allows for adaptability to changing conditions.
Step-by-step explanation:
Out of the given habitat options, the habitat most likely to harbor the most recently diverged species would be one that has experienced a burst of speciation, as noted in point 3, which describes an example of adaptive radiation. A biodiversity hotspot, defined in point 9, would contain a large number of endemic species, those found nowhere else in the world, which could also suggest recent divergence. Considering point 2, Genus B with a wider variety of genetic traits is more likely to survive post-disaster due to its genetic diversity. This directly influences the likelihood of recent species divergence as a result of adaptive responses to changing conditions.
