The correct answer is **D. degeneration**. Here's why:* **Deterioration** means a gradual decline or worsening of something.* **Degeneration** also means a gradual decline or worsening, often referring to a physical or mental state.The other options are incorrect:* **Repairment** means to fix or mend something.* **Conviction** means a strong belief or opinion.* **Improvement** means to get better or make something better.* **Enhancement** means to make something better or more appealing. Since the text likely discusses dementia, which involves a decline in cognitive function, "degeneration" is the most fitting synonym for "deterioration" in this context.
