Explanation:

As per the question, the above options states the true claim regarding the controlling idea of a text. The controlling idea is demonstrated as the idea that surrounds the entire content of the text. While writing an essay or any text controlling idea includes the topic as it primarily functions to explain and justify it.

The author's viewpoint establishes the credibility of the controlling idea into the mind of the audience and it also functions to convey the intended message of the text that the author wishes to convey to the audience.
