The correct answer is:
<span>[O say what stranger cause, yet unexplor'd,
Could make a gentle Belle reject a Lord?]
The poet is wondering why a girl would ever reject a man who is hitting on her and wants to marry her. It is implied that women had no say in this - that their marriage depended solely on the man and that they couldn't choose at all. The entire poem is quite satirical and meant to mock these kinds of ideas and behaviors.
</span>
The second statement is the most accurate.
Hope this helps!
I'm pretty sure the last one is incorrect as it become a constitution monarchy not a ruling power of England.
