Answer: Loess is the fine grained material that has been transported and deposited by the wind. The answer is <u>A.</u> 
Explanation:
Since the wind can carry these types of material (find grained) father than sand, and also higher up, they are generally found very far from their original place of origin. 
Loess is no larger than 50 micrometers in size. It is coarse in texture like clay, but finer than a grain of salt.
