B. Own words
A summary is a concise restatement of the central ideas of a text, written in the writer's own words. It involves paraphrasing the main points and essential information from the original text without copying large sections verbatim.
While a summary should capture the key ideas clearly and effectively, "best words" is not the correct definition. It emphasizes paraphrasing in the writer's own style.
A thesis statement is a concise statement that summarizes the main argument or position of an essay or paper, not a summary of a text.
Supporting ideas are secondary points that back up the main ideas in a text, but a summary focuses on the main or central ideas themselves.
Thus, the correct answer is B. Own words, as a summary condenses the original content while presenting it in the writer's own style.
