Which of these methods is not solely applicable to biological classifications?
a. whittaker’s classification
b. cladistics
c. linnaeus’s classification

Option B, Cladistics

Explanation:

In a biological classification system, organisms are grouped into different groups based on the similarity of physical (as per traditional classification systems) and genetic characteristics (as per modern classification systems).  

Whittaker has grouped the organisms into five kingdoms - Monera, Protista, Fungi, Plantae and Animalia based on their cellular structure, reproduction, feeding pattern and many other physical characteristics.  

However, Linnaeus’s classification group organisms into eight texas which are as follows -domain, kingdom, phylum, class, order, family, genus, and species.

However, Cladistics involves development of cladograms which are more or less similar to phylogenetic trees. Caldograms group organism based on the shared ancestry and descendants at each clade (group of organism also including ancestor species)

Hence, option B is correct
