Which of the following is not-a sea route?

Analyze the question You are asked to find the route that is not a sea route, meaning a route that cannot be travelled entirely by ship. To answer this, check whether every city on each route is a port or can be reached by sea.

Concept A sea route links ports across oceans and seas. Cities that are ports (or have sea access) can be connected by ship. Cities deep inland, far from any ocean or sea, cannot be part of a sea route.

Checking each option

• A. London → Moscow → Baghdad: London is a port on the River Thames. Moscow is a deeply inland city in Russia, not on any sea coast. Baghdad is also inland, on the River Tigris, and far from the Persian Gulf. A ship cannot sail this route from start to finish. Moscow and Baghdad make it a land or air route, not a sea route.
• B. London → Cape Town → Melbourne: All three are ports. It is a classic long-distance ocean route around Africa and across the Indian Ocean to Australia. It is a sea route.
• C. New York → London → Rotterdam: All three are major ports. It crosses the North Atlantic and the North Sea. It is a sea route.
• D. Sydney → Suez → London: Sydney is a port, Suez is the port at the southern end of the Suez Canal, and London is a port. This is a well-known sea route through the Indian Ocean, Red Sea, Suez Canal and Mediterranean. It is a sea route.

Answer Option A is the only one that includes inland cities, so it is the route that is not a sea route.

Tip For "which is not a sea route" questions, look for a city that is landlocked or far inland (such as Moscow, Baghdad, Kano or Johannesburg). Such a city breaks the sea route immediately. Also remember that Suez and Cape Town are key points on the Europe-to-Asia/Australia routes.
