We can define theory as:
"A logical-deductive or inductive and organized set of ideas that explain a given phenomenon, where the deductions are based on observations".
With this, we can see that the correct option is "To explain natural and physical phenomena"
Now let's explain this a little bit more.
Here we want to see the goal of a theory.

A theory wants to explain something. Someone sees a phenomenon, and in a need to understand it, uses the information that he/she has to try to explain it. Then he/she proceeds to do experiments to test if the theory is correct.
Concluding, the correct option is:
"To explain natural and physical phenomena"
