Suppose you had the program below, and you wanted to concatenate the values from the libname and memname columns to create a call to %Report3 for each row of data read. Which option would correctly run the program below and generate a result?

rc=dosubl(cats(%Report3,',libname,memname),')');

rc=dosubl(catx(%Report3(',catx(',',libname,memname),')'));

rc=dosubl(catx(%Report3,',libname,memname),')');

rc=dosubl(cats('%Report3(',catx(',',libname,memname),')'));
