The correct answer to the question "At_____, photography is a chemical process, during which a light-sensitive material is altered when exposed to light," is:
This is because the phrase "at its most basic" is a common English expression used to describe something in its simplest or most fundamental form. In this case, it is used to describe the basic chemical process of photography. The other options, "its basic," "the basic," and "its most basic," do not follow the correct grammatical structure for this expression.

Furthermore, the reference 4 provides a clear example of how the phrase is used in a sentence, reinforcing that "at its most basic" is the correct choice.
