Evaluate these commands which execute successfully:

Which two statements are true about the ORD_ITEMS table and the ORD_SEQ sequence? (Choose two.)

Sequence ORD_SEQ cycles back to 1 after every 5000 numbers and can cycle 20 times.
Any user inserting rows into table ORD_ITEMS must have been granted access to sequence ORD_SEQ.
Column ORD_NO gets the next number from sequence ORD_SEQ whenever a row is inserted into ORD_ITEMS and no explicit value is given for ORD_NO.
If sequence ORD_SEQ is dropped then the default value for column ORD_NO will be NULL for rows inserted into ORD_ITEMS.
Sequence ORD_SEQ is guaranteed not to generate duplicate numbers
