The correct answer for this one seems strange. I thought it would be "what children don't love to drink?"? I'm not sure though, so didn't report.
Correct answer: • What do children not love to drink? • What do children not like to drink?
Does "what children don't love to drink" mean "what sort of children don't like to drink"? If it is, it's not a correct translation. This sentence means, what sort of a drink children don't like to drink.
