Answer:
A differences in air pressure
Explanation:
As we know that flow of fluid is always due to pressure gradient.
here we know that pressure difference will apply force on the fluid due to which it has tendency to flow.
The force due to pressure difference is given by
[tex]F = \Delta P A[/tex]
now fluid has always a tendency to flow from higher pressure region to lower pressure region due to this force of pressure difference.
So wind flow is always following the same law of pressure difference due to which wind flows from region of high pressure to low pressure
so correct answer will be
A differences in air pressure
