As the picture shows, it was taken by a photographer on a sunny autumn morning. Please observe this picture carefully and find out the correct description of the physical knowledge contained in it.

A, as can be seen from the figure, there are small water droplets on the flower branches, which are formed by the cold liquefaction of water vapor in the air; Then this statement is correct and meets the meaning of the question.

B, the small water droplets attached to the flower branches are in a static state, so they must be affected by the balance force; Then this statement is correct and meets the meaning of the question.

C. The delicate flower branches in the picture are quite different from those without water drops, and they are curved, which must be the result of force; Then this statement is correct and meets the meaning of the question.

D, the shape of the water drop is a transparent object with a thick middle and a thin edge, which plays the role of a convex lens. Because the distance between flowers in the distance is very large, the flowers seen through it are real images, not virtual images; Then this statement is wrong and does not conform to the meaning of the question.

So choose a, b and C.
