An inference is something that is definitely true based on the information given in the passage
The information given in the passage can be summed up as: The fundamental laws that govern matter and energy, when applied to the universe over long enough cosmic timescales, can explain everything. The formation of literally everything in our universe can all be understood as something that emerges directly from the fundamental laws.
From this, we can say that the fundamental laws governing and explaining everything are the same. Thus, D is the correct answer.
