Hallier, Hutchinson, Takhtajan, Engler, and Prantl is proposed with the phylogenetic system of classification.

Such a system includes the classification of organisms on the basis of descent from a common ancestor. Also, it is based on evolutionary ancestry.

So, the correct option is ' All of the above' i.e. D.

• The process of developing an evolutionary history of organisms is called phylogeny. The unit of data used here is the character or trait. 
  
• Systematics deals with the evolutionary relationships between the organisms
  
• Taxonomy deals with classifying and naming organisms.
  
• Hierarchy is an arrangement of sequence in an increasing or decreasing order.
  

Phylogeny is the study of the organisms with respect to its evolution and the relationship with other organisms. The concept of phylogeny has been discovered by Ernst Haeckel. The term phylogeny deals with the study of the evolutionary history of an organism. The classification which is based on the evolutionary relationship of organisms is referred to as phylogenetic classification. The evolutionary changes, lineage and history are taken into account during the classification.  

• Gregor Johann Mendel is considered as the Father of Genetics
• Linnaeus is considered as the Father of Taxonomy by his great contributions in this field
• One of the prime systems o plant taxonomy was devised by Adolf Engler
• Har Gobind Khorana is well known for first to demonstrate the role of nucleotides in protein synthesis
• So the correct option is Linnaeus

• System Naturae, is the book that contains various species of animals, was written by Swedish Naturalist, Linnaeus, who is known as Father of taxonomy
• Charles Darwin was an English Naturalist who wrote the book 'On the origin of species' and famously known as Father of evolution
• Aristotle was a Greek philosopher and popularly known as Father of Zoology
• Alfred Russell Wallace was a British Naturalist who wrote the book ' The Malay Archipelago' and famed in developing the theory of Natural selection
• So the correct option is 'Linnaeus'.

• A person who studies the origin, evolution and variations in plants and also about the classification is referred as a taxonomist
• A person who studies about the characteristics, habits and habitats of animals is referred to be as a zoologist
• A person who studies about cultivation of crops, and their techniques is referred as an agriculturist
• A person who studies in detail about plants is called as botanist
• So, the correct option is 'Taxonomist'.
  

Phanerogamae are the sub-kingdom of kingdom Plantae. They include seed bearing and flowering plants. They are further grouped into angiosperms and gymnosperms 

Phylogenetic classification mainly depends on similarities and differences in their physical or genetic characteristics. The evolutionary relationship defined by the phylogenetic depends on the body symmetry, the pattern of embryonic development, the complexity of tissue organisation. Motility is a basic characteristic which is not prominent for a particular class rather it is common to all. It do not change with evolution.

• Michael Adanson was the first scientist to reject all the artificial systems and support the natural systems of classification.
  
• Natural system of classification is that in which all natural characteristics of plants both vegetative and reproductive characters are taken into consideration. It is purely natural as the knowledge of phyllogenicity was not detected 
• Natural system of classification is a biological classification based upon morphological and anatomical relationships and affinities
