Answer:
C
Explanation:
Option C is the correct answer. This is because it is the option that best revises the paragraph in order to convey the same meaning as that of the paragraph while maintaining a formal tone.
In the other options, you discover a little deviation from the meaning of the paragraph towards the end of each of the other revised paragraphs. Option C is the only option that maintained the meaning.
Other options also have a kind of informal tone but only Option C maintained a formal or official tone.
