Which of the following Statements stands true for Full outer-join? Select one: a. It pads tuples from the right relation that did not match any from the left relation with nulls and adds them to the result of the natural join. b. It takes all tuples in the right relation that did not match with any tuple in the right relation, pads the tuples with null values for all other attributes from the right relation, and add them to the result of the natural join. c. It takes all tuples in the left relation that did not match with any tuple in the right relation, pads the tuples with null values for all other attributes from the right relation, and add them to the result of the natural join. d. it pads tuples from the left relation that did not match any from the right relation, as well as tuples from the right relation that did not match any from the left relation, and adding them to the result of join.
