Explanation
As soon as you see variables in the answer choices, set up your scratch paper to Plug In.
Start with easy numbers like p = 2, x = 3, and y = −4. Of the answer choices, all work except choice (C), which can be eliminated. Now plug in different numbers: Since the variables are described as non-negative and non-positive, try making p, x, and y all 0. Now choices (A), (B), and (D)
all yield false statements and can be eliminated. The correct answers are choices (D) and (F).
Hence options D and F are correct.
