To allow for an appropriately randomized experiment, the population should be broad enough to include dogs with varying characteristics (like breed, age, and size) to assess the general effect of diet on activity levels across different types of dogs.
Among the given options, **Population #1: dogs in California** allows for a more diverse sample of dogs compared to the other two populations, which are limited to specific breeds and locations. This diversity can help ensure that the results of the experiment on diet and activity level are more generalizable.
Thus, the best option for an appropriately randomized experiment is **Population #1: dogs in California.**
