I'd say 9, since the three bits you have mentioned have to be multiplied by the three user groups (owner, group, others). rwxrwxrwx

9 is closest, but you may have forgotten about 3 more bits used for special access; setgid, setuid, and the sticky bit. Which makes 12. They are part of the inode that describes the file permissions and file type - the last 4 are the file type but not related to permissions, which is what the question asked.

Traditional Unix permissions are broken down into: so answer is 3 read (r) write (w) execute file/access directory (x) Each of those is stored as a bit, where 1 means permitted and 0 means not permitted.
