B: incorrect You should generally select the Unicode character set AL32UTF8, because it supports most languages of the world. C: incorrect Starting from Oracle Database 12c Release 2, if you use Oracle Universal Installer or Database Configuration Assistant (DBCA) to create the database, then the default database character set is AL32UTF8. A: correct Single-byte character sets result in better performance than multibyte character sets, and they also are the most efficient in terms of space requirements. E: incorrect Single-byte character sets result in better performance than multibyte character sets, and they also are the most efficient in terms of space requirements.
