Hiya,

I certainly think the answer is A (according to the CheckPoint pdf)

Upgrade the Management High Availability Servers
1. Synchronize the Standby SmartCenter Servers (SCSs) with the Active SCS by
selecting Synchronize in the Policy > Management High Availability window.
2. Upgrade all the SCSs in the organization.
3. Login to SmartDashboard via the Active SCS. For each Standby SCS, change
the software version in Check Point Products listbox of its network objects
window.
4. Synchronize the Standby SCSs with the Active SCS. The synchronization status
is expected to be collision. This occurs on account of the Upgrade operation.
5. Make sure that you select the Active SCS as the dominant SCS, in order that all
the Standby SCSs will be overwritten. Once again, synchronize the remaining
Standby SCSs to the Active SCS.

I hope this helps.
