D Correct answer
Explanation

IfNull is primarily a SQL function (like MySQL's IFNULL), not a DataStage transformer function. DataStage uses SetNull(), MakeNull(), NullToEmpty(), IsNull(), and NullToValue() for null handling. The question tests familiarity with DataStage-specific function names versus generic SQL functions.
