You are working on building a new Electronic Publications service that allows users to retrieve electronic copies of online books for display on specialized electronic reading devices. This service needs to contain two operations:
1. An operation that retrieves an entire book. This operation needs to receive a message based on a pre-defined "addBookRequest" element and then reply with a message based on the "addBookAcknowledgement" element.
2. An operation that retrieves information that describes a book. This operation needs to receive a message based on a pre-defined "getBooklnfoRequest" element and then reply with a message based on the "getBooklnfoResponse " element.
Examples of these XML fragments based on these four elements are shown here:

You are now tasked with creating an XML schema that will correctly validate these four XML fragments. Which of the following is correct?
