Which naming rule for the lion's scientific name Panthera leo is incorrectly used?

• A. The first letter of the genus is capitalized, and the species name is lowercase
• B. The two names are underlined separately
• C. The names are italicized together
• D. There is a space between the genus and species names

Answer: (B)

Binomial nomenclature uses two names to identify a species: genus and species. The genus name is always capitalized, the species name is lowercase, and the two names are written together in italics. If you’re handwriting, you underline the entire binomial as one single unit, not each word separately. There’s a space between the genus and species. Panthera leo follows this rule: Panthera is capitalized, leo is lowercase, and the pair is written with a space and in italics. The idea of underlining the two names separately goes against the standard practice of treating the binomial as one unit when underlined. That’s why this option is not correct. The other statements match how scientific names are properly formatted.
