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

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

@Kasi you are right.
Just check it once by opening the moment of inertia.

@Dhanya.
In case of udl then, deflection = 5wl^4/384EI.
So it is wrong.
In case of udl then, deflection = 5wl^4/384EI.
So it is wrong.

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.
