In Parkinson's disease, a resting tremor is a key symptom that typically manifests when the affected limb is at rest, meaning that it is not in motion. This characteristic is fundamental to distinguishing a resting tremor from other types of tremors, such as those associated with action or intention, which occur during voluntary movement. The presence of the tremor while the limb is stationary is often a defining feature of Parkinson's disease and is linked to the pathophysiological changes in the brain associated with the disorder.

The other choices highlight different aspects of tremors that are not typical for resting tremors. For instance, a tremor that improves or worsens with movement pertains more to essential tremor or postural tremor, which do not have the same resting component. The intermittent nature suggested in one choice also does not align with the consistent presentation seen in resting tremors of Parkinson's disease.
