Answer Details

Without our relentless campaigns, we might **never have been** sure of victory in the race for the National Assembly. This option is the most appropriate because it correctly conveys the meaning that, if not for our relentless campaigns, we would not have achieved or experienced a state of being sure of victory in the race for the National Assembly. The combination of "never" and "have been" in the option suggests that this is a past unrealized possibility that would not have occurred if certain actions (the relentless campaigns) were not undertaken.
