Answer 1

Answer:

B. the direction of the wind at the time it was deposited

Explanation:

Cross beds refers to those rock beds which are formed due to the deposition of bed forms such as dunes. These cross beds are the group of inclined layer which is formed due to the flowing of water or wind. These rock beds represents the movement or direction of wind and water at the time of deposition and as a result cross beds are formed. So we can say that cross beds were formed due to the direction of wind.
