Explanation:

To determine the correct order of body organization from smallest to largest, we analyze each option:

1. First option: Incorrect order (organism is largest, not smallest; organelle is smaller than cellular, etc.).
2. Second option: "Microscopic" is not a level of biological organization (levels are chemical, organelle, cellular, tissue, organ, system, organism).
3. Third option: Reverse order (starts with largest, ends with smallest).
4. Fourth option: Follows the correct biological hierarchy: Chemical (molecules, atoms) → Organelle (cell parts) → Cellular (cells) → Tissue (groups of cells) → Organ (groups of tissues) → System (groups of organs) → Organism (whole body).

Answer:

D. chemical, organelle, cellular, tissue, organ, system, organism.
