To answer this question, we need to understand the privileges related to updating comments on a sequence.
Option A) Control - This option is incorrect because the "Control" privilege does not specifically grant permission to update comments on a sequence.
Option B) Update - This option is incorrect because the "Update" privilege typically refers to the ability to update the actual data within a sequence, not the comments associated with it.
Option C) Usage - This option is incorrect because the "Usage" privilege generally refers to the ability to view or query the data within a sequence, not the ability to update comments.
Option D) Later - This option is correct because the "Later" privilege allows a user to update the comment on a sequence. This privilege specifically grants the ability to modify or update the comment associated with a sequence.
Therefore, the correct answer is Option D) Later. This option is correct because it grants the necessary privilege to update the comment on a sequence.
