If a driving force has the same frequency as a system's resonant frequency, the oscillation magnitude will be:

Explanation:
When a driving force vibrates at the system’s resonant frequency, energy is transferred most efficiently into the motion. Each push aligns with the system’s natural motion, so it adds to what’s already moving, causing the amplitude to grow. In real systems damping limits this growth to a large but finite size, whereas in an ideal undamped system it would keep increasing without bound. So the oscillation magnitude becomes greater than at other driving frequencies.
