Answer:
C.
Step-by-step explanation:
Paraphrase can be defined as a phenomenon of restating or rewording of a text or a paragraph. It is done to avoid the risk of plagiarism (word to word copying of other's work; also known as literary theft).
Paraphrasing can be an important tool in a research paper in which plagiarism is strictly prohibited.
The given statement is an example of paraphrasing as it restates the speech of President Obama in the writer's words.
So, the correct answer is option C.
