Explanation:

The biological organization hierarchy typically goes from cell (smallest unit) to tissue, then organ, then organ system, then organism. The shape marked with "o" is before "Tissue", so it should be "Cell" as cells form tissues. Option B is Cell, which fits the hierarchy (Cell → Tissue → Organ → Organ System → Organism).

Answer:

B. Cell
