– the number adverse events in each system organ class (AESOC)

– within each level of system organ class, the number of adverse events with each preferred term (AEPT).

Which code produces the counts requested?
A . proc freq data=AE;
tables AESOC AEPT;
run;
B . proc freq data=AE;
tables AESOC*AEPT;
run;
C . proc freq data=AE;
tables AESOC (AEPT);
run;
D . proc freq data=AE:
tables AESOC, AEPT;
run;
