Concept:The kingdom split after Solomon's reign, and the northern part kept the name Israel.
Explanation:After King Solomon died, his son Rehoboam became ruler, but he treated the people harshly.
The ten northern tribes rebelled and broke away from the house of David.
This created two kingdoms: Israel in the north and Judah in the south.
Jeroboam, the son of Nebat, was the man God chose to lead the northern tribes.
He became the first king over the northern kingdom of Israel, while Rehoboam ruled only Judah in the south.
Therefore, in biblical history, Jeroboam stands as the first king of the divided kingdom of Israel.
Answer:Jeroboam (Option A).
