Cause them v necks and them teeth
An interest group (also called an advocacy group, lobbying group,
pressure group, or special interest) is a group, however loosely or
tightly organized, that is determined to encourage or prevent changes in
public policy without trying to be elected.
So based off this knowledge, we can eliminate C. :)
I don't think it's A or B because they are more concerned with change

So going with this definition, I'd go with D ;)
Medieval age lasted for more than thousand years. The medieval age is formerly proclaimed to be Dark Age not because it was dark but because nothing was known.
After the collapse of Greek and Roman civilizations, the whole of Europe came under the supremacy of the churches at that which gained control. It was called as nothing was known or studied about the political structure that prevailed during that period.
Dark Age does not actually refer to the time when people spent much of their time in darkness. It simply means that nothing came into light from the period when great civilizations came to an end.
