**The reasoning**
The twelve tribes of Israel are named after Jacob's twelve sons. Here's the key story: Jacob (also called Israel) had twelve sons — Reuben, Simeon, Levi, Judah, Dan, Naphtali, Gad, Asher, Issachar, Zebulun, Joseph, and Benjamin. Each son became the ancestor of a tribe, so the tribes are literally his descendants. The name "Israel" comes from Jacob himself — God renamed him Israel after he wrestled with an angel. So "tribes of Israel" = "tribes descended from Jacob/Israel."
**Why the wrong options tempt you**
**Abraham** — He's Jacob's grandfather and the father of the Hebrew people, so students think "founding father = tribes." But Abraham → Isaac → Jacob is the lineage; the *twelve* tribes specifically come from Jacob's generation.
**Moses** — He led the Israelites out of Egypt, so he's closely associated with them, but he didn't father the tribes; they already existed.
**Adam** — Too far back; he's the father of all humanity, not specifically Israel.
**Quick takeaway**
Remember: **Jacob = Israel = 12 sons = 12 tribes.** The tribes carry his name because they literally came from his family.
