Hello! Well, this is just a common sense question, lets think about this on terms of weight, a bus is about 33,000 pounds, and you would need over a ton of helium to lift that force up. The other three would be the lightest so according to the weight of the Bus, that would be the answer. Good Luck!

Answer:

a bus

Explanation:

It takes more force to hold a heavier object up in the air because gravity pulls down with more force on objects that have more mass. A bus is the heaviest object, so it would take the most force to hold up in the air.
