To accurately determine which statement is best supported by the provided diagram, I would need to see the diagram itself. However, I can guide you on how to analyze the evolutionary relationships typically represented in such diagrams (like a phylogenetic tree):
1. **Look for common ancestors**: If two or more species diverge from a single branch, they share a common ancestor.
2. **Order of evolution**: Generally, species that are shown lower on the diagram evolved earlier (more ancestral), while those higher up evolved later.
3. **Direct relationships**: A species that directly branches off from another is more closely related to that species than to others that branch off elsewhere.
Based on these principles, you can evaluate the statements:
- **a**: If both species T and U are shown as branching from species X, this could support a, but it depends on the diagram layout.
- **b**: If there is a clear direct path from species T to species S with no other branches intervening, this would support b.
- **c**: If species U is on a branch that clearly diverges before species S but after species X, then this could support c.
- **d**: If species S is shown as a direct ancestor of both species U and V, this supports d.
Without the diagram, you will need to apply these guidelines to decide which statement is best supported.
