The main idea here is the overall prognosis for cervical radiculopathy as reported in the material. It notes a high likelihood of improvement with appropriate treatment, and the percentage given to capture that favorable outcome is 85-90%.

This range best fits the typical data because most patients experience meaningful recovery in symptoms and function with nonoperative care (like physical therapy, medications, and sometimes injections), and many improve within weeks to a few months. It reflects a strong but not universal improvement: not everyone regains every symptom completely, and some cases require further intervention if deficits persist.

The other options don’t fit the intended prognosis: 70% or 50% would underestimate the generally good outcomes described, and 100% is unrealistic since a portion of patients may have residual symptoms or require escalation to surgical management.
