Explanation:

Let’s break it down:

- Option 1: dims – “Dims the land like the sun” doesn’t work. The sun brightens; it doesn’t dim. This doesn’t fit the idea of wisdom.

- Option 2: darkens – Same problem here. The sun doesn’t darken, and neither does wisdom. It’s usually a force for good and light.

- Option 3: spreads – While “spreads” technically could work, it’s vague. “Spreads” like the sun doesn’t bring to mind light or wisdom reaching out.

- Option 4: illuminates – Now, this makes sense. “Illuminates the land like the sun” paints a clear picture of a wise king’s wisdom shining across his land. That’s exactly the kind of imagery the sentence is going for.

The correct answer is Option 4: illuminates.
