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.

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.

@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.
