Based on the scientific names, which TWO organisms are most closely related

The two organisms that are most closely related are Corvus splendens (house crow) and Corvus corax (common raven).

Explanation: Both of these birds belong to the genus Corvus, which indicates they share a more recent common ancestor compared to the other options listed. Taxonomy often uses the genus as an indicator of relatedness; organisms within the same genus are typically more closely related than those in different genera.
