The correct answer is:
**C. Mechanical energy cracks the inner tube, which starts a reaction that transforms chemical energy into light energy.**
In a glow stick, the activation of the chemical reaction occurs when the inner tube is broken, and this mechanical action allows the chemicals to mix. The stored chemical energy then transforms into light energy through a chemiluminescent reaction.
