Q. The only landlocked country in south-east Asia is:

The correct answer is: a) Laos

Explanation: A landlocked country is one that is entirely surrounded by land and does not have access to the sea. In Southeast Asia, Laos is the only landlocked country. It is bordered by China to the north, Vietnam to the east, Cambodia to the southeast, Thailand to the west, and Myanmar to the northwest. Unlike other countries in the region such as Thailand, Vietnam, and Cambodia, which have coastlines along seas or oceans, Laos has no direct access to any sea or ocean.
