Final answer:
David's candidacy as king is supported by archaeological evidence and his achievements as a leader.
Step-by-step explanation:
The question of whether David was the obvious choice to be king is a complex one, as there are conflicting accounts in the Bible. However, there is evidence from the Tel Dan stele that supports the existence of King David's kingdom. Additionally, David's ability to establish a capital at Jerusalem, create a professional army, and make alliances with neighboring kingdoms suggests that he was a capable leader. Based on these factors, it can be argued that David was a strong candidate and a viable choice to be king.
