How is the author's name written at the end of a scientific name printed?

Correct answer: In normal Roman letters, not italicized

Correct answer: A. In a scientific name such as Mangifera indica L., the genus and specific epithet are written in italics when printed, or underlined separately when handwritten. The author citation placed after the scientific name is different: it is normally printed in ordinary Roman type, not italics. The author’s name may be abbreviated, as L. represents Linnaeus, but it does not have to be written entirely in capital letters. B is wrong because italics apply to the organism’s binomial, not normally to the author citation. C is wrong because author names are not required to be all capitals. D is wrong for standard printed presentation; underlining is mainly a handwritten substitute for italics. Memory cue: “name italicized, author regular.”
