D Correct answer
Explanation

Options A, B, and C show valid SORT key specifier syntax using the {} notation with field names and optional sorting directions. Option D uses 'desc cust_id' which is NOT valid Ab Initio SORT component syntax - the correct format would be '{cust_id descending}' within braces, not as a separate keyword before the field name.
