In a cladogram, organisms that share a common ancestor and have more closely related evolutionary relationships are placed on the same branch. To determine which organisms share a common ancestor, we consider the relationships of these organisms based on evolutionary traits.
Given the choices:
a) **whale and water boatman** - These are not closely related; whales are mammals and water boatmen are insects.
b) **praying mantis and water boatman** - Both are insects, but they belong to different orders, so they don't share a recent common ancestor.
c) **praying mantis and whale** - These are also not closely related; one is an insect and the other is a mammal.
d) **praying mantis and cat** - Again, these are from very different classes (insect vs. mammal).
Given these considerations, none of the options provided seem to clearly represent organisms that would be on the same branch as they traditionally are classified into very different taxonomic groups.
However, the best option for common ancestry among these would typically be between the **whale and cat** because they both belong to the class Mammalia. If we assume these were not options and were not included in the choices, it seems like a mistake in the question format, as none of the listed pairs are closely aligned. Please double-check the options or criteria given.
