Answer Key / Explanation : (d) -

(d)

Biological classification is the scientific procedure of arranging organisms, into groups and sub-groups on the basis of their similarities and dissimilarities and placing the groups in a hierarchy of categories

Whittaker has used five criteria for delimiting the different kingdoms

(i) Complexity of cell structure, i.e., prokaryotic and eukaryotic

(ii) Complexity of body structure or structural organisation of unicellular and multicellular

(iii) Mode of nutrition, which is divergent in multicellular kingdoms, photoautotrophy in Plantae, absorptive heterotrophy in Fungi and ingestive heterotrophy in Animalia

(iv) Ecological life style like producers (Plantae) decomposers (Fungi) and consumer (Animalia)

(v) Phylogenetic relationships
