structures? (Choose two.)

A.An extent cannot spread across data files.

B.A segment cannot spread across data files.

C.A data file can belong to only one tablespace.

D.A data file can have only one segment created in it.

E.A data block can spread across multiple data files as it can consist of multiple operating system (OS)
