From the given choices the true statement is Surface winds blow parallel to isobars.
Answer: Option B
<u>Explanation:</u>
The winds which flow near the isobars, flow in the parallel direction of the isobars. They are not absolutely parallel to each other but are this much parallel that the purpose of the flight planning can be fulfilled with this.
These winds flow in perpendicular position to isobars which are present at that particular surface and they flow in this direction due to the acting of the force of friction in that area. This force of friction can also change the direction and the flow of the wind.
