I'm pretty sure the answer is B, isolationism.
The majority of landowners were men, so not many women voted. There were more white landowners than black land owners in the colonies, resulting in the fact that African Americans were unable to vote. An influx of new colonists from Spain and France purchased land, as a result, they made a larger voting population than the British colonists.
The Church was extremely influential during the medieval ages. They held the ability to disperse information because churches were scattered all over Europe. This enabled their network of monks and priests to share information very fast. Furthermore, they collected taxes from peasants very often in the form of goods (farm produce for example), this made them very rich. They also had control over decisions which different rulers did as they could exile them which wasn't something any ruler wanted.
