You want to use RMAN to create compressed backups. Which statement is true about the compression algorithms that RMAN can use？（）
- A The BZIP2 compression algorithm consumes more CPU resources than the ZLIB compression algorithm.
- B The ZLIB compression algorithm consumes more CPU resources than the BZIP2 compression algorithm.
- C The ZLIB compression algorithm provides maximum compression and produces smaller backups than the BZIP2 compression algorithm.
- D Only the BZIP2 compression algorithm can be used to make compressed backups to disk.
