The STORES table has a column START_DATE of data type DATE, containing the datethe row...

For filtering rows based on the START_DATE within the last 25 months:

C. WHERE MONTHS_BETWEEN(SYSDATE, start_date)<=25: This WHERE clause correctly uses the MONTHS_BETWEEN function to compute the number of months between the current date (SYSDATE) and the START_DATE column. It checks if the difference is 25 months or fewer, correctly applying the condition.

Incorrect options:

A: The TO_NUMBER usage is incorrect for date arithmetic in this context.

B: ADD_MONTHS used in this manner would incorrectly calculate dates in the future rather than comparing past dates.

D: The MONTHS_BETWEEN function should have SYSDATE as the first argument to calculate past months correctly.
