D should be the correct answer, width and depth will change about the axis you are considering that is Ixx or Iyy but the length will be the same, so the answer should be option D.

I think all of them are correct because in the deflation formula wL3/48EI where I= bh3/12.

Option A, B & C are correct in the case of a rectangular beam.
Deflection = 5wl4 ÷ 384EI for uploading,
= Wl^3÷48EI for point load etc.
Where I = bd^3/12.
Deflection is directly proportional to weight or load & length.
Deflection is inversely proportional to width and the cube of depth.
