The best revision to this is that "The rule of thirds is a composition rule that divides the scene into three rows and three columns." The other choices may sound correct but this is the best way to paraphrase the statement given.
The answer to your question would be that the best revision of this sentence is the following one: The rule of thirds is a composition rule that divides the scene into three rows and three columns.
This is the best revision because it uses all of the words in the original statement and it also uses the active voice. What is more, the sentence reads fluently as it is idiomatic and does not sound odd at all.
