They have used 3EIL. Which is wrong? L should not be there.

The deflection at C is true, since b & a .
Therefore, maximum deflection occurs in CB.
Therefore, maximum deflection occurs in CB.

Here in question given (Wa2b2/3EIL). So read the question carefully.
If you put a = b = (L/2). Then it satisfies the equation as we know that for simply supported beam max deflection is,
(WL^3/48EI).
So given answer is wrong.
Option A is the correct answer.

Here it is a simply supported beam with eccentric loading (wa2b2/3eil). Which is absolutely correct. Hence by substitution a = L/2, we can get the maximum deflection at mid point.

I too say that the correct answer will be A.

w.b/(9root3 EIL) * (a^2 + 2ab)^(3/2).

@All.
Check the unit of the answer. Here that is not in meter but meter^2.
So, FALSE(B).

It's a simply supported beam but the load is not symmetric so, it will produce max deflection at the point where external load is applied.
