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.

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.

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

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

Ymax =Wa/9*3EIL(l^2-a^2)^3/2.
