Which of the following is an example of figure-ground perception?

A) an inkblot on a sheet of white paper
B) a cloud in an otherwise cloudless sky
C) a single tealeaf at the bottom of an empty teacup
D) all of the above

All of the options involve figure-ground perception as they require the viewer to differentiate between the main object or figure and the background or ground. In the inkblot on a sheet of white paper, the inkblot is the figure and the white paper is the ground. In a cloud in an otherwise cloudless sky, the cloud is the figure and the blue sky is the ground. In the single tealeaf at the bottom of an empty teacup, the tealeaf is the figure and the empty cup is the ground.
