Correct Answer : 2
Exp : OBS option will let SAS know last observation to process. FIRSTOBS option will let SAS know first observation to process. So for first proc print FIRSTOBS =100 and OBS (i like
to call it LASTOBS) = 500, so there are 401 observation (including 100th observation) processed by it.
