Organ systems (cardiovascular system) contain organs.
Organs (heart) contain cells.
Cells (red blood cell) are the smallest unit here.
Step 2: Correct order: man, cardiovascular system, heart, red blood cell.
Step 3: Evaluate options.
Option A: man, heart, red blood cell → Incorrect (skips cardiovascular system).
Option B: cardiovascular system, heart, red blood cell → Incorrect (misses man/organism).
Option C: man, cardiovascular system, heart, red blood cell → Correct (matches order).
Option D: cardiovascular system, heart, man → Incorrect (wrong order).
