We cannot make a conclusive statement about the variation in ratings between girls and boys. (Option C is unsupported.)
We can conclude that at least half of the boys (i.e. more than half, based on the given mean and range) rated peanut butter a 9 or 10. (Option D is true.)

Yes, that's correct. At least half of the boys rated the peanut butter a 9 or 10 on the scale of 1 to 10.
