AIIMS 2017 Biology Taxonomy MCQ Question

Classical taxonomy primarily relies on the similarities and dissimilarities in the behavior of organisms, which can provide insights into their evolutionary relationships and ecological roles. While morphological traits (option A) are important, they do not encompass the full range of behavioral characteristics that can influence classification. Habitat (option B) is relevant but does not directly inform taxonomic relationships, as organisms from different habitats can share similar behaviors. Thus, option C is the most comprehensive in reflecting the principles of classical taxonomy.
