Answer:
C. The Egyptian nationalization of the Suez Canal and the international reaction.
Explanation:
The Suez Crisis, also known as the Sinai War and Second Arab-Israeli war, was a military conflict between Egypt, supported by the Arab countries, and Israel, supported by France and the UK, that took place in 1956 in the Sinai region. The cause of this war was the nationalization of the Suez Canal by the Egyptian president, Gamal Abdel Nasser. Before the nationalization, the canal was in the hands of France and the UK and, since it was built, it was one of the most important trade routes in the world. The Egyptian president, Gamal Abdel Nasser, was a nationalist, pan-Arab, and socialist leader who decided to nationalize the Suez Canal to stop foreign intervention in his country and to get the profit of the commerce through the canal. Since Nasser was the main leader of the Arab world, he took the lead against Israel and increased the military pressure against this country and negatively affected the Israeli economy by blocking the straits of Tiran. The war finished with the military victory of Israel, the re-opening of the straits of Tiran, and a political victory of Nasser who kept the nationalization of the canal.
