Step-by-Step Solution
The complete worked solution.
Every step explained - no skipped algebra.
In the absence of damping, when a system is driven at its natural frequency (resonance), the energy keeps adding up, causing the amplitude to increase indefinitely in theory. In real systems, damping prevents this from becoming infinite.
Final Answer: Option C - The amplitude increases without limit.
