exploits and its relevant payload

how can i find out what payload(s) can be use/executed along with an exploit?

for example, i can use an exploit called exploit/windows/smb/ms08_067_netapi. Right after that i set the payload to windows/adduser. what other payload can i use here. how can i find out this information or is there a specific command in metasploit that i can run to figure this out?

I am not asking specifically for ms08_067_netapi exploit.

thank you
