According to the figure, the answer is correct but according to c's position the right answer is:- (Wa^2c^3)/384EI.

Wa^2b^2/3EIL is deflection under the applied load, it is not the maximum deflection.

The equation given in the question expresses the value of Deflection at the point of application of load. But maximum deflection will be somewhere between the point of application and midpoint of the beam. So this equation DOESN'T represent MAXIMUM deflection and the statement will be FALSE.

This equation is correct. So the answer must be A.

Use MOMENT AREA METHOD, you will get max. Deflection as Wa^3b/3LEI.

It's simply supported beam maximum deflection occurs at the midpoint of load applied.

Does it require constant bending moment equation for Macaulay method?

In simply supported beams deflection =Wl^3/48EI.
In simpy supported with UDL deflection =5Wl^4/384EI.
In simpy supported with UDL deflection =5Wl^4/384EI.

The expression given is True, put, a=b=l/2, and you will get the expression, Wl^3/48EI.
