Option B is the correct solution- It uses the BY group processing with question id and answer, which ensures the count is reset for each unique answer within each question. The code initializes answer_count to 0 at the beginning of each new question and answer combination and increments it for each occurrence. Options A and D only reset the count at the start of each question, not each answer within the question. Options C and E are incorrect, as they either do not reset the count per question or do not group by both question id and answer.

The correct answer is option C. The ORDER= option within the PROC EXPORT statement allows you to specify the order of variables in the exported file. It takes a list of variables enclosed in parentheses- The correct syntax is ORDER=(Product_Name Product_lD Price). Option A exports the data without specifying an order- Option B and D specify invalid ORDER= options. Option E specifies the ASCENDING order, which is not what the question asks.

Option B is correct. The DATE9. format in SAS displays dates in the ddMMMyyyy format, which corresponds to the example given (25JUN2019). This format writes dates with a two-digit day, a three-character month abbreviation, and a four-digit year. The other options do not match the correct format:
* A is incorrect because ddMMMyy9. format would display a two-digit year.
* C is incorrect because there is no such format as Ddmmmyyyy9. in standard SAS formats.
* D is incorrect because Dmy9. does not correspond to the required format.
