Interpret what the author is telling you and use key words to find a main idea
C would be the answer to this
"Today nobody brought his or her instrument" is correct. It is common for people to use "their" in a sentence like this, but "his or her" is the more proper term.
I mean you may be physically free but mentally captured. For example, you work at a restaurant and you are free to leave whenever you want, but your boss treats you badly. He's always in your head and thoughts because you know that if you don't please him he might fire you and you need your job. Another example could also be that you are physically healthy but mentally ill. For example: You may have multiple personalities and even though you don't have a wounded leg or arm you are internally enslaved to the other personalities which tell you what to do. These are just a few examples of how you can be physically free and at the same mind enslaved.
