Constraints can be added to a table during the initial creation using the CREATE TABLE command, or after the fact using the ALTER TABLE command. Both options are valid ways to add constraints to a table, so D is the correct answer. While primary keys automatically create a constraint, it is not the only way to add constraints to a table.
