To answer this question, let's go through each option:
Option A) SYS privileges - This option is incorrect because the operations performed by the DELETE_TEMP_TABLE procedure are not performed under the SYS privileges. The SYS privileges are typically reserved for the system administrator.
Option B) Your privileges - This option is incorrect because the operations performed by the DELETE_TEMP_TABLE procedure are not performed under your privileges. Your privileges are separate from the privileges granted to user A.
Option C) Public privileges - This option is incorrect because the operations performed by the DELETE_TEMP_TABLE procedure are not performed under the public privileges. Public privileges typically refer to privileges granted to all users.
Option D) User A's privileges - This option is correct. When user A executes the DELETE_TEMP_TABLE procedure, the operations are performed under user A's privileges. The EXECUTE privilege granted to user A on the procedure allows user A to execute the procedure and perform the operations specified within it.
Therefore, the correct answer is option D. The operations performed by the DELETE_TEMP_TABLE procedure are performed under user A's privileges.
