Artists use different techniques to make their prints unique. Which print displays the artist's use of the silkscreen technique?

Im pretty sure that the frog is the silkscreening one.

Explanation:

Silkscreening is a form of art that involves the artis carving or stensiling divits or dents into a strong material and then rubbing ink on it to fill in the empty areas and printed on a paper, canvas, etc. most of these look similar to the picture of the frog.
