Answer 1

Answer: (B)

Classification involves hierarchy of steps, in which each step represents a rank or category, called taxonomic category or taxon. All taxa together constitute a taxonomic hierarchy as species $\to$ Genus $\to$ Family $\to$ Order $\to$ Class $\to$ Phylum or division $\to$ Kingdom.
Most common characters among individual members are found in taxon species. Common characters decrease from species to kingdom and members of a kingdom have least number of common characters. Similarly, complexity of classification decreases from species to kingdom. follows:
