The value of the variable Discount in the output data set is 2000. A note that conversion has taken place is written to the SAS log.

The value of the variable Discount in the output data set is missing. A note in the SAS log refers to invalid numeric data.

The variable Discount in the output data set is set to zero. No messages are written to the SAS log.

Correct Answer: C

In SAS, when a numeric operation is attempted on a variable that is defined as a character, the value will be invalid for numeric operations. In the given program, 'Cost' is assigned the character value '$20,000'. When the SAS program attempts to calculate the value of 'Discount' as .10*Cost, it will fail because Cost is not recognized as a valid numeric value. This results in the value of 'Discount' being set to missing, and a note in the SAS log referring to invalid numeric data.
