An essay in which each sentence and paragraph flows logically from one to the next.
Step-by-step explanation:
An essay that uses straightforward vocabulary and sentence structure (option B) may still be lacking clearness of ideas.
An essay in which the writer's personality is clearly distinguishable (option C) is not the best example of clarity as it relates to essay writing. The thing is that the distinguishability of the writer's personality has nothing to do with clarity of his or her writing.
An essay in which every paragraph and sentence supports a single thesis (option D) is not a correct option either because 'single' does not mean 'the same', so they may be supporting different theses.
That leaves us only one choice - A.
