A will log it to the file Error.log in XML format.
B does not use the exception so will not log anything valuable.
C will write a message to the output window
D will broadcast a message but there are no listeners to actually write the log

So both A and C pass the requirements. A is not recommended to use (listener without source) and B is also not recommended to use (TraceSource is replacement of Trace).
