Selected Answer: DF
D is true. However, I change my mind. It is F not D as multiple sources and Oracle doc. says when a NULL value is used in arithmetic operation it will cause error in run-time.

Selected Answer: DE
D is correct as for variables like NUMBER, DATE,VARCHAR2 if they are not initialized during declaration - they will be initialized to NULL during runtime. & E is correct as when an arithmetic operation is performed with an NULL variable the outcome will be NULL as well per Oracle.

C is a trap because yes any sql might fail if invoking user doesn't have privilege. But D is correct because all variables are inistialized to NULL. E is correct because anything + null is null
