You create an XML Web service named LatLong that converts street addresses to latitude and longitude coordinates. Your company charges for this service and allows only existing customers to use the service.If a customer is not passed as part of a SOAP header, you want the service to refuse the request. You want these service refusal messages to be logged to an event log named LatLongLog. You anticipate that there will be a lot of these log entries over time. A string object named refusalMessage contains the message to log.Which code segment should you use?

A.Dim log As New EventLog("LatLongLog")log.WriteEntry(refusalMessage, EventLogEntryType.Error)

B.Dim log As New EventLog("LatLongLog") log.Source = "LatLongLog"log.WriteEntry(refusalMessage, EventLogEntryType.Error)C . If Not EventLog.SourceExists("LatLongSource") ThenEventLog.CreateEventSource("LatLongSource", "LatLongLog") End IfEventLog.WriteEntry("LatLongSource", refusalMessage, EventLogEntryType .Error)D. If Not EventLog.SourceExists("LatLongSource") ThenEventLog.CreateEventSource ("LatLongSource", "LatLongLog") End IfDim log As New EventLog ("LatLongLog")log.WriteEntry(refusalMessage, EventLogEntryType.Error)
