The correct answer is - C. the San Andreas fault.
San Francisco, as most of the western of California, is lying in close proximity to the San Andreas fault. This fault is a continental transform fault that is formed as a result of the transform boundary between the Pacific plate and the North American plate, with a small plate lying in between them. Because of the horizontal movement of the plates and the pressure they cause to one another, there's constant adjustments inside the crust, and that contributes to lot of earthquakes in the region. One of those earthquakes was the San Francisco earthquake of 1906, a very strong and devastating earthquake, often considered as the worst earthquake in the history of the United States.

From altering the environment humans receive the benefit of multiple resources, such as wood which they receive from cutting down trees. Deforestation gives humans the benefit of having more land accessible for the public, as trees taken down by deforestation allows for humans to build public locations such as parks, and provides land for houses to be built on. Overall, altering the environment gives humans the benefit of having more resources, along with land that they are able to use for housing and livestock farms, which once again provide more resources for the public.
The layer of the sun that radiates most of the light that reaches Earth is called the photosphere.
I hope this helps!
