b) Homo sapiens

c) Homo sapiens

d) Homo Sapiens

Answer 1

Hint: ICZN stands for International Code of zoological Nomenclature for animals. Every living organism has a unique scientific name. ICZN has a set of rules to assign a scientific name for animals. Initially let us understand what is binomial nomenclature.

Complete Answer:

Binomial nomenclature is a formal system of naming living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name or a scientific name, informally called as Latin name.

There are bodies of binomial nomenclature for naming animals and plants.

1. ICZN- International Code of zoological Nomenclature for animals.

2. ICBN- International code of Binomial Nomenclature for plants.

According to the rules of binomial nomenclature of ICZN,

- The first part of the name is the generic name that identifies the genus to which the species belong.

- The second part is the specific name or specific epithet that indicates the species inside the genus.

- The first letter of the first part of the genus name is always capitalized while that of the second part is not, even if it is a proper noun.

Therefore the correct answer is (b) Homo sapiens.

Note: Every species has a unique scientific name. Scientific names are always italicised. Genus names are unique within each kingdom, but can be repeated between kingdoms. It is possible for two or more species to share the same genus name.
