In binomial nomenclature, the genus name is capitalized.

• A. Lower case
• B. Capitalized
• C. Italicized
• D. Underlined

Answer: (B)

In binomial nomenclature, the first part of the name denotes the genus and is written with a capital letter because it is a proper noun that identifies a group of closely related species. The second part, the species epithet, is written in lowercase to distinguish the specific species within that genus. Together they are usually italicized in print (or underlined when handwriting).

For example, Homo sapiens uses a capital H for the genus Homo, and a lowercase sapiens for the species epithet, with the whole name typically in italics. This capitalization rule keeps the rank clear and consistent across organisms.

So the correct choice reflects that the genus name is capitalized. The other options would not align with standard naming conventions for genus.
