- A Savanna is a rolling grassland scattered with shrubs and isolated trees, which can be found between a tropical rainforest and desert biome.
- Savannas are also known as tropical grasslands. These types of grassland are found in a wide band on either side of the equator on the edges of tropical rainforests.

The correct answer is option 'C' - tropical savanna.
Vegetation in tropical savannas is characterized by a large expanse of grassland with scattered trees and shrubs. These areas are typically found between tropical rainforests and tropical steppes and deserts. The presence of flat-topped trees is also a distinguishing feature of tropical savannas.
- **Grassland with scattered trees and shrubs**: Tropical savannas are characterized by vast areas covered with grasses, with trees and shrubs scattered throughout. These grasslands are often dominated by species such as buffalo grass, kangaroo grass, and spear grass. The trees present in this type of vegetation are typically short and widely spaced.
- **Location between tropical rainforest and tropical steppes and deserts**: Tropical savannas are found in regions where the climate transitions from the wetter conditions of the tropical rainforest to the drier conditions of the tropical steppes and deserts. These areas are typically located in the intertropical convergence zone, where trade winds from the northern and southern hemispheres meet.
- **Flat-topped trees**: One distinctive feature of tropical savannas is the presence of flat-topped trees. These trees, known as umbrella trees or acacia trees, have a flattened crown that helps them maximize their exposure to sunlight. The flat shape of their crowns also helps to reduce water loss through transpiration.
Tropical savannas are characterized by a unique combination of grassland, scattered trees, and shrubs. The vegetation in these areas has adapted to the specific climatic conditions, including the seasonal rainfall patterns and the transition from wetter to drier environments. This type of vegetation supports a diverse range of wildlife, including large herbivores such as elephants, giraffes, and zebras, as well as predators like lions and cheetahs.
Overall, the combination of grassland, scattered trees, and flat-topped trees is indicative of the vegetation type known as tropical savanna.
