Answer: B
There are three different modes of encryption (as opposed to the algorithm used). These are transparent mode, password-based encryption, and dual-mode encryption, which encompasses both modes of encryption. For transparent encryption, you will need to create a wallet, and it must be open. Transparent encryption will then occur automatically after you have issued the CONFIGURE ENCRYPTION FOR DATABASE ON or CONFIGURE ENCRYPTION FOR TABLESPACE ON command.

Transparent encryption will then occur automatically after you have issued the CONFIGURE ENCRYPTION FOR DATABASE ON or CONFIGURE ENCRYPTION FOR TABLESPACE ON command.
