The correct option is Habitat diversity.

To understand why this is the correct answer, let us break down the concept of biodiversity and its different levels:
Biodiversity, or biological diversity, refers to the variety of life on Earth and is typically measured at three distinct levels: genetic diversity, species diversity, and ecosystem or habitat diversity.

1. Habitat Diversity:
Habitat diversity refers specifically to the range of different habitats, niches, and ecological processes in a given geographic area or country. A habitat is the physical environment in which an organism lives. When a country features many different habitat types—such as deserts, rainforests, wetlands, grasslands, and marine ecosystems—it is described as having a high degree of habitat diversity. Therefore, the presence of several different habitat types directly defines habitat diversity.

2. Distinguishing from other options:
- Genetic diversity refers to the total number of genetic characteristics or variation within a single species.
- Species diversity refers to the number of different species (species richness) and their relative abundance (species evenness) within a particular area.
- Biodiversity is the broad, overarching term that encompasses all levels of biological variation, including genetic, species, and ecosystem/habitat diversity. While a country with many habitats is biodiverse, the most precise and specific term for the variety of physical environments/habitat types itself is habitat diversity.
