Question Detail

This question is vague. Taxonomy, in its broadest sense, is the science of describing, naming, and classifying organisms. While it draws on phylogeny (evolutionary relationships), chemotaxonomy (using chemical data), and experimental taxonomy, its fundamental task is descriptive classification. However, 'descriptive taxonomy' is a bit redundant. Perhaps the question means taxonomy includes all these aspects. Given the options, A is the most direct answer, as taxonomy is fundamentally about description and classification.
