Option 2.

Technicians distinguish kingdoms by biological traits such as cell type (prokaryote vs. eukaryote), cellular organization (unicellular vs. multicellular), methods of nutrition (autotrophy vs. heterotrophy), cell‑wall composition (peptidoglycan, chitin, cellulose, or none), and reproductive strategies (sexual vs. asexual), plus molecular/biochemical features (e.g., rRNA sequences, membrane lipids) when needed.
