4. All the extents would be of size 1 MB.
Which three options would you choose to create the tablespace? (Choose three.)
A) tablespace with AUTOEXTEND enabled
B) tablespace with dictionary-managed extents
C) tablespace with a uniform. extent allocation of 1 MB
D) tablespace with segment space management as manual
