Given the following table and XML data stored in the CONTACTINFO column: CREATE TABLE clients( id INT PRIMARY KEY NOT NULL, name VARCHAR(50), status VARCHAR(10), contactinfo XML ) 25 EastCreek Toronto OntarioM8X-3T6 4165551358 9051112222 9051112222 by fax What is the result of the following XQuery expression? for $y in db2-fn:xmlcolumn('CLIENTS.CONTACTINFO')/Client//fax return $y

The XQuery expression uses db2-fn:xmlcolumn to access XML data and searches for fax elements within the Client hierarchy. Looking at the XML structure, the fax element contains '9051112222'. The expression uses //fax which searches for fax elements at any depth under Client. The result returns the fax element with its content, which is 9051112222. Option A (4165551358) appears elsewhere in the document but is not in a fax element. Options C and D are incorrect - the expression is valid and does find a matching fax element.
