- C Long-term preservation of dried specimens in herbaria

Correct answer: B. Study of evolutionary relationships among organisms
Explanation: Taxonomy covers identification, naming, and classification; systematics is broader, also incorporating the study of evolutionary relationships (phylogeny) among taxa.
The taxonomic hierarchy narrows from Kingdom (broadest, covering the most organisms but fewest shared traits) down to Species (narrowest, fewest organisms but most shared traits) - every level in between is a progressively more specific subset of the one above it.
