Here is the DocCD location for NTP:
http://www.cisco.com/en/US/docs/ios/netmgmt/configuration/guide/nm_basic_sys_manage_ps6350_TSD_Products_Configuration_Guide_Chapter.html#wp1001075
I believe that the peer command sets NTP to "symmetric active mode" which
allows the local and remote device to syncronize with each other and allow
them to use the better source of time.
The server command simply means that the local device will syncronize time
from the server.
Based on your question I would use solution A.
