It should be all of these.

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.

B and C both are correct as I=bh^3/12.
Hence deflection is inversely proportional to the width and cube of the depth of the beam.

In every equation for rectangular beam, there is a term variable/EI (I= bh^3/12) in the denominator, while the rest of variables change with loading conditions, therefore the given answer is correct.

Both B and C are correct see the moment of inertia formula.

As per my knowledge, the answer will be (E)... because;
(a) not directly proportional to its weight but the load.
(b) I may be 1/12 db^3.
(c) same as (b).
(d) power of l changes with the load.
