What term describes blocking off ports and roads to prevent movement during a war?

• A. Embargo
• B. Blockade
• C. Siege
• D. Invasion

Answer: (B)

Blocking off ports and roads during war is called a blockade. It aims to stop ships and travelers from moving in or out, cutting off trade and supplies so the enemy doesn’t get what it needs and is weakened without fighting everywhere at once. A blockade is about actively sealing off routes in war, not just a general policy or an attack on a single city. An embargo is a trade restriction, not a military tactic to control movement in a war zone. A siege focuses on surrounding a specific city to force surrender, usually on land. An invasion is an armed attack to take over territory, not simply preventing movement.
