The best effective thesis statements are both the first ("Hollembeak's review of the high school's play is fun and entertaining to read") and third ("In her editorial, Mellie writes convincingly of the need for high school classes to begin later in the morning") options.

The first and third statements are the only ones which state a convincing thesis about an argument. Both of them are informative about what is the object argued and present a clear idea of the main point made on that.

Fourth option does apply to the question as well because it is not a thesis, that is just exploring the content of an argument made, clarifying ideas for readers. And fifth option does not apply to the question too, because it is not a thesis, that is just a description of an information previously given, it only characterizes an informative statement, not an effective thesis.
