Statement C is the true statement! "All 6 girls weigh exactly the same." Watch the animation again. When each side of the scale had the same number of girls, it was in equibrium! That means all 6 sextuplets weigh exactly the same! By the way, each girl weighs 110 Earth lbs., so altogether, they weigh a total of 660 Earth lbs.!
