View the exhibit and examine the structure of the STORES table.

You want to display the NAME of the store along with the ADDRESS, START_DATE, PROPERTY_PRICE, and the projected property price, which is 115% of property price.

The stores displayed must have START_DATE in the range of 36 months starting from 01-Jan-2000 and above.

Which SQL statement would get the desired output?

SELECT name, concat (address| | ','| |city| |', ', country) AS full_address,
start_date,
property_price, property_price*115/100
FROM stores
WHERE MONTHS_BETWEEN (start_date, '01-JAN-2000') <=36;
SELECT name, concat (address| | ','| |city| |', ', country) AS full_address,
start_date,
property_price, property_price*115/100
FROM stores
WHERE TO_NUMBER(start_date-TO_DATE('01-JAN-2000','DD-MON-RRRR')) <=36;
SELECT name, address||','||city||','||country AS full_address,
start_date,
property_price, property_price*115/100
FROM stores
WHERE MONTHS_BETWEEN (start_date, TO_DATE('01-JAN-2000','DD-MON-RRRR')) <=36;
SELECT name, concat (address||','| |city| |', ', country) AS full_address,
start_date,
property_price, property_price*115/100
FROM stores
WHERE MONTHS_BETWEEN (start_date, TO_DATE('01-JAN-2000','DD-MON-RRRR')) <=36;

SQL>SELECT * FROM books_transactions ORDER BY 3;

What is the outcome on execution?

Rows are displayed in the order that they are stored in the table only for the three rows with the lowest values in the key column.
Rows are displayed in the order that they are stored in the table only for the first three rows.
Rows are displayed sorted in ascending order of the values in the third column in the table.
