A fossilized fish is found that has jaws but no true bones. This fossil belongs to D on the cladogram in the image attached.
so, the correct option is D.
<h2>Explanation:</h2>
A cladogram is a diagram used to represent a hypothetical relationship between groups of animals, called a phylogeny. A cladogram is used by a scientist studying phylogenetic systematics to visualize the groups of organisms being compared, how they are related, and their most common ancestors.
A cladogram belongs to the branching tree-like diagram used to demonstrate an evolutionary association between the species. A point of divergence exhibit two branching lines of descendence, suggesting an evolutionary divergence from a common ancestor.
As these fossils exhibit jaws but do not possess true bones it can be presumed that they originated 395 million years ago in the mid of the Devonian period.
