The correct answer is A. Defend your point of view…
Explanation:
An argumentative text, which is the type of text requested in an argumentative prompt, is one in which the writer needs to present his position or point of view about a subject and then use arguments along with reliable evidence to explain, support and defend this position. Because of this, the words that indicate an argumentative writing prompt is " Defend your point of view…" as this is the main objective or purpose in this type of texts. Also, other options are incorrect as "Explain how" belongs to an expository writing prompt, "Compare and contrast..." to a comparing and contrasting text and "Summarize" to a summary.
