Check Answer
Answer: D

注解:The CONTENTS procedure shows the contents of a SAS data set and prints the directory of the SAS library. As the libref is omitted, SAS uses the default library WORK, and  _ALL_ represents all data sets in that library. SAS lists the data sets in WORK library followed by the contents of each data set.
