The answer is: B
Explanation
The correct option is B: Palestine and Israel.
The West Bank is the larger of the two Palestinian territories (the other being the Gaza Strip) that are claimed by the State of Palestine as part of its envisioned state, along with East Jerusalem.
However, the West Bank has been under Israeli occupation since 1967, when Israel captured it from Jordan in the Six-Day War². Israel has built many settlements in the West Bank, which are considered illegal under international law.
The status and borders of the West Bank are a major source of conflict between Israelis and Palestinians, and a key issue in any peace negotiations.
