Linnaeus is considered father of taxonomy and was first to use the binomial nomenclature for organisms in his book “Species Plantarum, 1753” in which he gave a generic name to each species. The generic names was followed by trivial name that represented the specific epithet and hence, the system of binomial nomenclature; option B is the correct answer. Benthum and Hooker proposed the most elaborate natural classification of seed plants in their three volume book “Genera Plantarum, 1863-83”. This makes options A and C incorrect as their work was published much later than that of Linnaeus. Darwin is best known for his theory of natural selection to explain the process of evolution. Thus, the correct answer is option B. 

On the basis of hierarchy of characteristics, the last two units of classification are genus and species. The organism belonging to same genus and species are very much similar.

The 10th edition of 'Systema Naturae' was a book written by Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced the binomial nomenclature for animals.
Thus, the answer is option (B) - 'Systema naturae'.

Brassica nigra is the botanical name of black mustard. 

Philosophia Botanica was published by the Swedish naturalist Carl Linnaeus in 1751 who greatly influenced the development of botanical taxonomy and systematics. It is the first textbook of descriptive systematic botany and botanical Latin. It also contains Linnaeus's first published description of his binomial nomenclature.

The binomial nomenclature of the Touch-me-not plant is Mimosa pudica. This plant is known as touch me not plant because the plant shows a type of nastic movement. Whenever the plant is touched, the leaflets get folded. The stimulus is passed from one branch to the entire branch of the plants. The leaves of the complete plant get folded in response to the touch.

• Binomial nomenclature system was proposed by Carl Linnaeus for the scientific naming of all the plants and animals. Linnaeus proposed the scientific name of plants in his book 'Species Plantarum'.
  
• In binomial nomenclature, each scientific name has two components-generic names (genus) and specific name (species) E.g., Mangifera indica Linn. Mangifera is the genus name and indica is the species name.
  

The current system of International code of botanical nomenclature (ICBN) was adapted to assign the scientific name to plants. It was adapted in 1978 after the twelfth International Botanical Congress held in 1975 to follow the rules for naming the plants. The fifth International Botanical Congress was also held in 1930, at Cambridge (England). So, the correct option is C.
