Question one: I think it’s C, because I tend to see these videos more thought out- but that might just be in the side of the internet that I’m on. I wouldn’t do A because it’s not an informational podcast, it’s the background music for a movie (which is related, but movies aren’t always thought out well)
Question two: D. I say this because of my personal experience, and I know it probably isn’t C or B, and is definitely not A.
Question three: C. I think this one is self explanatory.
