The Suez Canal, the Strait of Hormuz, and the Strait of Gibraltar are important geographical points because they control access to vital trade routes.

Option 1 is incorrect. These waterways do not prevent attacks on bordering nations. While they may have security measures in place to protect against piracy and other unlawful activities, their primary purpose is not to prevent attacks on neighboring countries.

Option 2 is incorrect. These waterways do not prohibit the movement of ships carrying nuclear weapons. Their main function is to facilitate the movement of commercial ships and promote trade between countries.

Option 3 is incorrect. These waterways do not unite Russian access to warm water points. While Russia does have access to some warm water ports, such as those on the Black Sea, the Suez Canal, the Strait of Hormuz, and the Strait of Gibraltar do not specifically serve this purpose.

Option 4 is the correct answer. These waterways control access to vital trade routes. They provide shortcuts between different regions, allowing for efficient transportation of goods and facilitating global trade.
