28. David wants to update the 'quantity' of a product in his database to reflect the new stock availability. Which SQL statement should David use?
UPDATE product SET quantity = 50 WHERE product_id = 123;
INSERT INTO product (quantity) VALUES (50) WHERE product_id = 123;
DELETE FROM product WHERE quantity = 50 AND product_id d=123;
ALTER TABLE product SET quantity = 50 WHERE product_id id=123
