Answer:
A). Continental volcanic arc
Explanation:
As per the question, the phrase 'continental volcanic arc' does not fit the pattern as it is 'formed through the reduction of the oceanic plate under the continental plate.' While the other three 'continental rise,' 'continental slope,' and 'continental shelf' together contribute to make the 'continental margin.' It is the area that covers the boundary of the continental crust that contains mostly floating materials with three different portions with distinct depths at the verge of the rise, slope, and shelf levels. Thus, option A is the correct answer.
