The correct answer is option 4, which states that the horizontal wind circulation near the Earth`s surface is due to the pressure gradient, frictional force, and Coriolis force.

1. Pressure gradient: This refers to the change in atmospheric pressure over a given distance. Air moves from higher pressure areas to lower pressure areas, creating horizontal wind circulation.

2. Frictional force: When air moves near the Earth`s surface, it encounters friction with the surface. This friction slows down the movement of air, causing it to converge and create areas of high pressure, while also diverging and creating areas of low pressure. This pressure difference leads to horizontal wind circulation.

3. Coriolis force: This force is caused by the rotation of the Earth. As air moves horizontally, it is deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This deflection, known as the Coriolis force, influences the direction of wind circulation.

Therefore, all three factors - pressure gradient, frictional force, and Coriolis force - contribute to the horizontal wind circulation near the Earth`s surface.
