* A: This statement will not execute successfully because you cannot subtract a DAY interval from a DATE directly. SYSDATE needs to be cast to a TIMESTAMP first.
* B: This statement is correct. It adds an interval of '1' DAY to the current TIMESTAMP.
* C: This statement is correct. It subtracts an interval of '1' MINUTE from '1' DAY.
* D: This statement will not execute successfully. In Oracle, you cannot add intervals of different date fields (DAY and MONTH) directly.
* E: This statement has a syntax error with the quotes around INTERVAL and a misspelling, it should be
'INTERVAL'.
Oracle Database 12c SQL supports interval arithmetic as described in the SQL Language Reference documentation.
