View the Exhibit and examine the structure of the ORDER_ITEMS and ORDERS tables.

You are asked to retrieve the ORDER_ID, PRODUCT_ID, and total price (UNIT_PRICE multiplied by QUANTITY), where the total price is greater than 50,000.

You executed the following SQL statement:

SELECT order_id, product_id, unit_price*quantity "Total Price"

FROM order_items

WHERE unit_price*quantity > 50000

NATURAL JOIN orders;

B) The statement would not execute because the USING keyword is missing in the NATURAL JOIN clause.

C) The statement would execute and provide the desired result.

D) The statement would not execute because the ON keyword is missing in the NATURAL JOIN clause.
