Which of the following is the scientific name for Ficus?

The scientific name for Ficus is Ficus sp. The term "sp." is an abbreviation for "species," which is used to refer to a group of related plants within the genus Ficus when their specific species is not identified. Ficus is a genus that includes many species, such as the common fig (Ficus carica) and rubber tree (Ficus elastica). Using "Ficus sp." indicates a generalized reference to any species within the Ficus genus, making it the correct answer to the question.

The other options refer to different genera and species. Philodendron is a separate genus altogether, while Nephrolepis exaltata is the scientific name for the Boston fern, and Schefflera is a different genus that includes species like the umbrella tree. Each of these choices represents a distinct group of plants unrelated to the Ficus genus.
