Answer:
The Sinai Peninsula.
Explanation:
The Camp David Accords of 1978 was a diplomatic talk between Israel and Egypt brokered by US President Jimmy Carter. This historical talk between the Egyptian President and Israel's Prime Minister would later chalk out some issues between the two nations.
With several issues including boundaries and possessions involved, the two countries of Israel and Egypt had always found it hard to broker any peace deals. But with the involvement of US President Jimmy Carter, the two leaders, President Anwar Sadat and Prime Minister Menachem Begin, were able to have peace talks at Camp David, the country retreat of the President of the United States. Despite initial misunderstandings and even reluctance to offer peace deals, an agreement was concluded after a twelve-day talk.
One significant agreement of that talk was that Israel agreed to withdraw from the Sinai Peninsula, thereby allowing Egypt to regain the land.
Thus, the correct answer is the second option.
