My choice was B.

Answer 1

Stressed syllables are pronounced more loudly than unstressed syllables.

The word “agree” is unstressed, then stressed. Say it out loud. Can you hear it?
The word “mighty” is stressed, then unstressed. Can you hear that?

Now read line 37 out loud, slowly. What do you hear?

Yes, C.
