Eddy could add "D. a few closeup branches on the left and right of his frame" as a foreground element to his photo based on the options provided. Closeup branches put on the frame's edges can give depth and interest to the composition, attracting the viewer's attention to the main subject in the background. The other possibilities given do not represent different foreground elements that would be appropriate for Eddy's composition.
Not sure if that answered your question♀️
