Doubly landlocked means surrounded only by landlocked countries. Liechtenstein (surrounded by Switzerland and Austria) and Uzbekistan (surrounded by Afghanistan, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan - all landlocked) are the only two doubly landlocked countries. Swaziland borders Mozambique (has coastline), and Turkmenistan borders the Caspian Sea (connected to oceans). The answer is correct.
