Fill the gap with the most appropriate option from the list provided.Without our relentless campaigns we might _____ sure of victory in the race for the National Assembly?

Answer Details

The correct option is "never have been". This means that the speaker's campaign efforts were crucial in achieving victory in the race for the National Assembly. The use of "never" and "have been" in this order creates a negative construction that emphasizes the importance of the campaigns.
