B. True. CURRENT_TIMESTAMP returns the current date and time in the session time zone, which is determined by the SESSIONTIMEZONE setting.

E. True. CURRENT_TIMESTAMP returns a value of the data type TIMESTAMP WITH TIME ZONE.

A and D are incorrect because CURRENT_TIMESTAMP reflects the session time zone, not DBTIMEZONE. C is incorrect because CURRENT_DATE returns the current date with no time component, whereas CURRENT_TIMESTAMP includes both date and time. F is incorrect because SYSTIMESTAMP returns the current date and time from the system clock in the time zone of the database server, which can differ from the session's time zone affecting CURRENT_TIMESTAMP.
