Which one of the following countries does not border the Caspian Sea?

Correct Option

Armenia is a landlocked country located in the South Caucasus region. It lies to the west of Azerbaijan and does not possess a coastline along the Caspian Sea. Consequently, it does not share a border with the Caspian Sea.

Incorrect Options

The Caspian Sea is recognized as the world's largest enclosed inland body of water. It is bordered by five countries:

• Azerbaijan: This country borders the Caspian Sea to its southwest.
• Kazakhstan: This country borders the Caspian Sea to its northeast.
• Turkmenistan: This country borders the Caspian Sea to its southeast.

The other two countries bordering the Caspian Sea are Russia (to the northwest) and Iran (to the south). Therefore, Azerbaijan, Kazakhstan, and Turkmenistan all have coastlines along the Caspian Sea and are considered riparian states.
