Answer:
ALTER TABLE orders
MODIFY (amount DEFAULT 250)
Explanation:
- ALTER TABLE statement is used to modify "amount" column in the existing "orders" table
- MODIFY (amount DEFAULT 250) is used to set the default value 250 of the "amount" column.
Therefore if the supervisor wants the amount column to be configured to accept a default value of 250, then "ALTER TABLE orders MODIFY (amount DEFAULT 250) " statement should be issued.

Explanation: Sequence diagram is the diagram that displays about the connection of the objects in a sequential manner. The sequence depicted through the vertical lines in parallel form was about the object function and the horizontal line showed interaction between them for the exchange of the information.
