The given figure shows a cantilever of span ‘L’ subjected to a concentrated load ‘P’ and a moment ‘M’ at the free end. Deflection at the free end is given by

A

$$\frac{PL^2}{2EI} + \frac{ML^2}{3EI}$$

B

$$\frac{ML^2}{2EI} + \frac{PL^3}{48EI}$$

C

$$\frac{ML^2}{3EI} + \frac{PL^3}{2EI}$$

D

$$\frac{ML^2}{2EI} + \frac{PL^3}{3EI}$$
