Answer:
D). Strip-mining should be tightly controlled in this region to reduce its pollution of water resources, its destruction of the land, and its devastating effects on people's lives.
Explanation:
A thesis statement is defined as a brief statement presented at the beginning of an essay to display the central idea of the essay and the author's stand on it.
As per the question, the most appropriate thesis statement to answer the question 'why should strip-mining be controlled?' would be the last option as it not only states the author's central claim that he/she is going to deal with but also displays his position logically. It is also argumentative as it can be debated as some may disagree with this claim. Thus, option D is the correct answer.
