Answer:
The answer to your question would be that the most effective substitute for the sentence is the following one: In the library, josephine read the children a story about a whale. That is, the correct option would be A.
Explanation:
The revised version of the sentence includes an introductory phrase with the prepositional phrase (in the library). Sentence B makes it seem as if Josephine read to a whale about children. Then, sentence C separates the indirect object from the direct object (about a whale in the library to the children), which makes the construction sound odd. Finally, D is written incorrectly, there shouldn't be a comma before to.
