I don't have kids yet, but I would go with C. I have seen parents struggle and struggle with their kids only wanting potatoes or chicken nuggets or PB&Js. I love to eat a variety of things, and having a kid that loves them too would be ideal.
As a former "picky kid", I'll say most people outgrow it, and it's only a power struggle if you make it a power struggle. Kids have more sensitive tastebuds which is why so many are picky.
