The .gb country code top-level domain is the ISO 3166-1 alpha-2 code for the United Kingdom, but .uk is much more commonly used in practice.

East Timor (Timor-Leste) changed its country code top-level domain from .tp to .tl after gaining independence from Indonesia in 2002.

The .su top-level domain was assigned to the Soviet Union (USSR) in 1991. After the Soviet Union dissolved later that year, .su became a legacy domain that continued to exist. Russia, as the successor state to the Soviet Union, is the country most closely associated with the .su domain, though it now uses .ru as its primary country code.

.mo is the country code top-level domain (ccTLD) assigned to Macau, a special administrative region of China. Mexico uses .mx, Mozambique uses .mz, and Montserrat uses .ms.

South American rainforests (C) are dense tropical forests - completely different. African savannas (D) are the correct match - both are grassland ecosystems with similar topography.

Latin America refers to countries in the Western Hemisphere (Americas) south of the United States where Romance languages (Spanish, Portuguese, French) are spoken.
