It collides with block B and sticks to it. The A - B combination collides elastically with block C. Which of the following statement is (are) true about the velocity of block B and C.
Options
A.Velocity of the block C after collision is 2/3 v towards right
B.Velocity of the A-B combination after collision is 
towards left
towards leftC.velocity of the A - B combination after collision is 
towards left
towards leftD.Velocity of the block C after collision is towards right
