activities.

Explanation:

The text states the Western Deffufa required a large number of workers, took significant time, and cost rulers a lot of money to feed the labor force. This indicates the kingdom had the resources and authority to organize and fund such a large project. The text also notes mudbrick was a common material, so the second option is incorrect. No mention of military use is made, so the third option is unsupported.

Answer:

The Kerman Kingdom must have been wealthy and powerful in order to build it.
