Jawaban:

A. Because

Penjelasan:

The correct answer is (a) because.

The sentence implies that the newspaper faced legal action or was taken to court because of an article it published about the government. The word "prosecuted" indicates a legal action against the newspaper. The word "because" is used to indicate the reason for the legal action. Therefore, option (a) is the correct answer. The other options do not convey the same meaning as "because" in this context. "Because of" and "as" are synonymous with "due to" and "since" respectively, but they do not convey the idea of legal action. "That is why" is a phrase that indicates a cause-and-effect relationship, but it is not appropriate in this context.
