The amount of air resistance to the object is most affected by its speed, cross sectional area, and the air density.
When, the object's speed is high, the air resistance will only have very minimal effect to it. Different is true with the cross-sectional area as the larger the cross-sectional area, the higher the air resistance acting on the object. Lastly, if the density of air is high then, it will tend to stay near the Earth's surface and not rise higher above hence, it will cause a decreased amount of air resistance.
The answers to this item are A, D, E.
