The option “E” is incorrect only on Oracle 10G R1 but is correct for the Oracle 10G R2.

The valid answers for Oracle 10G R2 would be “C,D,E”

According to Oracle documentation:

– From Oracle® Database SQL Reference 10g Release 1 (10.1)
ALTER TABLE
Restrictions on the shrink_clause

Segment shrink is not supported for LOB segments even if CASCADE is specified.
