Biological classification (taxonomy): Identify the most inclusive taxonomic category — the highest rank in the standard hierarchy. Consider the usual school-level hierarchy: Species → Genus → Family → Order → Class → Phylum/Division → Kingdom. Choose the correct highest category.

Given data

• We must pick the most inclusive (highest) taxonomic rank from common school-level categories.

Concept / Approach
The standard hierarchy is: Species < Genus < Family < Order < Class < Phylum/Division < Kingdom. (Some modern systems add Domain above Kingdom, but the classic question expects Kingdom.)

Reasoning
Among the options, Kingdom is above Phylum/Division and therefore is the most inclusive.

Common pitfalls

• Choosing Phylum/Division and forgetting that Kingdom sits above it.

Final Answer
Kingdom is the most inclusive among the listed ranks.
