Answer:
Geostrophic wind D) flows parallel to contour lines of upper-air pressure .
Explanation:
Geostrophic wind -
Air parcel generally moves from higher pressure to lower pressure due to pressure gradient force and left or right deflection due to coriolis force. When this deflection takes place a time comes when pressure gradient force and coriolis force becomes equal and the air parcel moves parallel to isobar then the winds are called geostrophic winds .

The innermost layer or the lower most layer of the Sun's atmosphere is called the photosphere. It is the visible surface of the sun that we are most familiar with. The sun is a ball of gas; however, the solid shape we see is actually just a layer which is about 100 km thick. The correct answer to this question is letter "C. Photosphere".
