Final answer:
The valid syntax for a PROC EXPORT statement in SAS is option (b), specifying the dataset, dbms as 'csv', and the outfile path properly.
Step-by-step explanation:
The student is asking about the correct syntax for the PROC EXPORT statement in SAS, which is used to export data to external files. Among the options provided, the one with the valid syntax is option (b), which correctly specifies the 'data=' option to identify the SAS dataset, the 'dbms=csv' to define the type of file, and the 'outfile=' option to specify the destination file path.
The correct syntax is:
proc export data=your-data-set dbms=csv outfile="c:\temp\your-file.csv"; run;
In this command, you should replace your-data-set with the name of the SAS dataset you want to export and your-file.csv with the filename you wish to use for your CSV file.
