I would say either B or D but I think the better answer would be D.
Answer:
Due to each state having an equal number of senators, states with a small population have the same power in the Senate as states with a larger population
Explanation:
Because each state has 2 senators, states like Wyoming(which has under 600,000 people) have the same power as California(with well over 35 million people). This is actually on purpose, as the writers of the constitution wanted to avoid a situation where Virginia(by far the most populous state at the time of the writing of the constitution) controlled politics in the entire country, especially since the states were much less united in their infancy.
Many people criticize this aspect of the Senate, as it allows a minority of the population to make laws for the majority, but it is still an open question that is actively debated today. The question itself is worded in a way that seems to portray this topic in a negative light, but it's best to maintain an objective tone when answering unless the question asks you to defend a position or your opinion on a topic. I hope this has helped.
