The holotype is a specimen or illustration which is designated as the representative of a species and is used for identification of the new specimen. A lectotype is a specimen or any other material which is selected from original material as cited by the author when holotype is not available. It is used in absence/non-availability of the holotype. The paratype is the specimen/ material which does not serve as holotype/isotype/syntypes. Thus, the correct answer is option B.
