The main idea here is the typical prognosis of cervical radiculopathy. Most people with this condition recover well with appropriate treatment. About 85-90% regain normal function or are left with only mild residual symptoms after the initial episode. This favorable outcome is usually achieved with nonoperative care—things like rest from aggravating activities, anti-inflammatory medications, physical therapy, cervical stabilization exercises, and education about posture and activity modification. Surgery is considered mainly for those with significant or progressive neurologic deficits or those who do not improve with conservative treatment.

So, the reason this option fits best is that it reflects the common clinical course: a large majority improve substantially without needing invasive procedures, with only a minority experiencing ongoing issues.
