• A. Power of attorney
• B. Nuncupative will
• C. Augmented estate
• D. Solemn probate

Answer: (D)

Proving a will and administering an estate through a formal court process is called solemn probate. This formal, court-supervised procedure validates the will, appoints an executor or administrator, and typically requires notice to heirs and creditors plus formal hearings. The other terms describe different concepts: power of attorney is a lifetime arrangement granting authority to another person; a nuncupative will is an oral will that may be recognized only under certain conditions; and an augmented estate is a concept used to calculate rights for certain heirs and is not about the probate process.
