Result
Your answer: β€”  Β·  Correct: B
Explanation

According to the rules of binomial nomenclature established by Carl Linnaeus and governed by codes like the International Code of Zoological Nomenclature (ICZN), a biological name must consist of two parts: the genus and the specific epithet [3]. The first word, representing the genus, must always be capitalized [2]. The second word, the specific epithet, must never be capitalized, even if it is derived from a proper noun [3]. Both components should ideally be italicized in print or underlined when handwritten to indicate their Latinized nature [2]. For the organism in question, 'Amoeba' is the genus and 'proteus' is the specific epithet [1]. Therefore, 'Amoeba proteus' is the only correct format as it follows the mandatory capitalization convention where the genus starts with an uppercase letter and the species remains entirely lowercase [3].
