Read the excerpt from dr. martin luther king’s "letter from birmingham jail."if i sought to answer all the criticisms that cross my desk, my secretaries would have little time for anything other than such correspondence in the course of the day, and i would have no time for constructive work. what is the author’s purpose for including this sentence? - to emphasize the productivity of his daily routine- to undermine the significance of his critics’ letter- to establish the impressive credentials of his staff- to explain the nature of his profession

I believe the best answer to be B) To undermine the significance of his critics' letter.

Explanation:

Dr. Martin Luther King is, in those few lines, addressing his critics in a short and effective manner. He is showing his audience he is aware there is criticism against him - that very criticism comes to him in the form of letters. However, it not so important as to prevent him from doing "constructive work". Dr. King is basically admitting that paying attention to criticism doesn't do anyone any good, since it gets nothing of value done. Thus, he chooses to work in what is truly significant, leaving his critics free to keep on writing but aware that they cannot undermine his work.
