Sorry, my internet connection is dying with windows 10 insider previews. 
I was right, apple 2c doesn't have them.

The manual mentions them by saying:

"(The //c uses the version of the 65C02 produced by NCR Corporation. 
Another version, produced by Rockwell International Corporation, 
supports all of the NCR instructions and four additional ones called SMB 
(set memory bit), RMB (reset memory bit), BBS (branch on bit set), and 
BBR (branch on bit reset). You cannot use these instructions on the //c.) "
