You define your national character set as AL16UTF16. What datatypes will store Unicode data? (Choose all that apply.)

Answer: A,C,F

Explanation: When the database's national character set is defined as UTF8 or AL16UTF16, you can store Unicode data in NVARCHAR2, NCLOB, and NCHAR datatypes . B is incorrect because the database character set applies to XMLTYPE data and not the national character set. D is incorrect because there is no such datatype as NBLOB. E is incorrect because LONG datatypes do not store Unicode data and they are supported only for backward compatibility using the database character set.
