Answered by GPT-5 mini AI
muscle cell → muscle tissue → stomach

This follows the correct simplest-to-most-complex order for body organization: cell → tissue → organ (the stomach). The other choices are either out of order or mix different systems (e.g., lungs are part of the respiratory, not circulatory).
