Error Identification: The word "whom" is incorrect because it is used for the object of a verb or preposition, whereas in this sentence, it should be "who", the subject.
Grammatical Explanation: "Who" is used when referring to the subject of a clause, while "whom" is used for the object. Here, "who" is required because the person wrote the book (subject).
Corrected sentence: "Can you tell me the name of the person who wrote the book?"
Explanation: Since "who" refers to the person performing the action of writing, the subject form "who" must be used.
