d, because the other three are very wide topics but you can explicitly discuss the effects and cause of MLK's bus boycottÂ
The correct answer is d. Martin Luther King, Jr.’s Montgomery bus boycott. Cause and effect writing is one of the genres of essays available for examination of students in college and in course of high school education. Martin Luther King, Jr.’s Montgomery bus boycott is narrow enough to address in a cause-and-effect essay.
