To answer this question, we need to understand the concept of the YEARCUTOFF option in SAS.
In SAS, the YEARCUTOFF option is used to interpret two-digit year values. It specifies the cutoff year for interpreting two-digit years as four-digit years.
If the YEARCUTOFF option is set to 1950, it means that any two-digit year values from 50 to 99 will be interpreted as 1950 to 1999, and any two-digit year values from 00 to 49 will be interpreted as 2000 to 2049.
The correct answer is A) 1950-2049. This time span is used to interpret two-digit year values if the YEARCUTOFF option is set to 1950.
