The division of the living world into three domains.
(a)Is strictly arbitrary.
(b)Was inspired by the morphological differences between archaea and bacteria.
(c)Emphasizes the greater importance of eukaryotes and was proposed by the early microscopists.
(d)Is strongly supported by data on rRNA sequences.

Hint: This is often a sequence that gives extensive and in-depth information about microbial communities on the skin and also allows interrogation of data about microbial communities without culturing.

Complete answer:
The division of the living world into three domains is strongly supported by data on rRNA sequences.
The three-domain system that may be a biological classification of organisms which was introduced by Carl Woese within the year 1990. This system divides cellular life forms into archaea, bacteria, and eukaryotic domains. The key difference from earlier classifications is that the splitting of archaea from bacteria. Woese proposed his point of view, on the thought of differences in 16S rRNA genes, that bacteria, archaea, and eukaryotes each arose separately from an ancestor with poorly developed genetic machinery, which can be called a progenitor.

Additional Information: -Carl Woese was an American microbiologist and biophysicist. Woese is legendary for outlining the Archaea (a new domain of life) in 1977 by phylogenetic taxonomy of 16S ribosomal RNA, a way he pioneered that revolutionized microbiology.
-Initially, Woese used the term "kingdom" to ask the three primary phylogenetic groupings, and this nomenclature was widely used until the term "domain" was adopted in the year 1990.
-This classification forms the idea of the fashionable classification which was made by studying the ribosomal RNA genes in these organisms.
-The organisms were placed in several groups thanks to the genetic diversity shown by these organisms for the ribosomal genes.
So, the right answer is,’Is strongly supported by data on rRNA sequences’.

Note: -The three-domain system that may be a biological classification of organisms which was introduced by Carl Woese.
-Woese proposed his point of view, on the thought of differences in 16S rRNA genes.
-The term "domain" was adopted in the year 1990.
