Answer:
A. California (CA)
D. Arizona (AZ)
Step-by-step explanation:
According to the map I have uploaded below, both California and Arizona have large areas that get more than 7.5 kWh/m2/day of sunlight.
These areas corresponds to the desert areas of Southeastern California, Most of Arizona, and Southern Nevada. In particular, the areas that sorround the Mojave Desert.
Some of these regions are among the sunniest in the world. For example, Yuma, Arizona, is the sunniest city in the world according to several statistics.
