Answer: Option C.

Step-by-step explanation:

As the speed of plane increases and it moves forward it allows to push air on the bottom of the wings of the plane which results in increasing the pressure

The fact of air pressure on top of planes wing decreases with the increase bin plane's speed is based on Bernoulli’s Principle which states that with the fast moving air, the pressure decreases.

Therefore,n when the plane moves up it's wing pushes air down and on the same time the air pressure decreases at the top of the wing, this difference between the high and low pressure allows the flight to lift up.

Hence, the correct option is C.
