Verified step by step guidance

1. Understand the concept of binomial nomenclature: It is a formal system of naming species of living organisms by giving each a name composed of two parts, both of which use Latin grammatical forms.
2. Recognize the two components of binomial nomenclature: The first part is the genus name, which is always capitalized, and the second part is the species name, which is not capitalized.
3. Learn the formatting rules: The entire scientific name is italicized (or underlined if handwritten). For example, *Homo sapiens* is the scientific name for humans.
4. Compare the given options: Eliminate choices that do not align with the definition of binomial nomenclature, such as assigning numbers or using paired statements.
5. Select the correct answer: Identify the option that describes binomial nomenclature as a system of naming organisms using two Latinized names—the genus and species.
