Answer:
B, look at explanation for reasoning
Explanation:
C) is incorrect because they were created by the Spanish government
A) is incomplete, and B is the main importance. If this has a different completion than 'they allowed the Native', there could be multiple correct answers?
B)
They were <em>not </em>the first settlements of California--however, they were the first European settlements, so I assume that this is what the answer was implying
The Spanish California missions were important as an effort to convert the local peoples/the Native Americans living there to Catholicism. They were also an effort to grow European territory.
The missions were the main way Spanish influence grew in California (because they [the Spanish] had missions, and there were no prior European settlements to represent them).
