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.
Hence deflection is inversely proportional to the width and cube of the depth of the beam.

Right @Mr. Asif.
Deflection is always inversely proportional to the moment of inertia in any case of loading.

In case of loading deflection is wl3/48 EI. So, Deflection is directly proportional to the weight of beam.

W is applied force.
Deflec=wl^3/48ei,
i=moment of inertia,
i=bd^3/12 so option c is correct.
Deflec=wl^3/48ei,
i=moment of inertia,
i=bd^3/12 so option c is correct.

It is also directly proportional to the cube of it's length. So option D can also be correct.

Only I=BD*3/12 will remain same in all condition of deflection. So, C option must be right.

All answers are correct, all of the above is a better option at the place of none of these.

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

According to me, the answer should be all the above read it carefully you will understand.

Deflection simply supported beam carrying point load at its mid point=wl^3/48EI.
