Final answer:
The preferred therapeutic option to resolve the underlying pathology in Graves' disease is radioactive ablation of overactive thyroid tissue.
Step-by-step explanation:
The preferred therapeutic option to resolve the underlying pathology in Graves' disease is c) Radioactive ablation of overactive thyroid tissue.
In Graves' disease, the thyroid gland produces excess thyroid hormone due to the presence of thyroid-stimulating immunoglobulin (TSI). Radioactive ablation involves the use of radioactive iodine (I-131) to destroy the overactive thyroid tissue.
This treatment option effectively reduces the production of thyroid hormone, bringing it back to normal levels.
