Three objects A,B and C are kept in a straight line on a frictionless horizontal surface

Three objects A,B and C are kept in a straight line on a frictionless horizontal surface.These have masses m,2m and m respectively.The object a moves towards b with a speed 9 m/s and makes an elastic collision with it. Thereafter, B makes completly inelastic collision with C.All motions occur on the same straight line.Find the final speed (in m/s) of the object C

Options

(a) 3 m/s
(b) 4 m/s
(c) 5 m/s
(d) 1 m/s
