Once I was friends with a very toxic person, but I stayed friends with them because they were good before. My difficult decision was to ask Myself if it was worth being friends with them because of how toxic they were. I ended up leaving and telling her why ofc. If i could have done things differently I wouldve stayed and stayed friends with her so I can teach her and make her a better person.
I would say ( b ) because you need to see what you already know before the experience and then show how much you learned by doing another assessment after the experience
