Answer: B

The dataset has ‘CHEM3’ and the if statement is looking for ‘chem3’…
Remember the SAS variables are not case-sensitive but the SAS DATA is…

Sridhar your answer clearly does not make sense. As SASGuru said SAS variables are not case sensitive but the Data is. So if you are searching for variable chem3 however the data is actually CHEM3 then you are not going to match. The result will be Unknown. The correct answer is B
