A ball moves over a fixed track as shown in the figure. From `A` and `B` the ball rolls without slipping. If surface `B` is frictionless and `K_(A),K_(B)` and `K_(C)` are kinetic energies of the ball at `A,B` and `C` respectively then:

A

`h_(A)gth_(C), K_(B)gtK_(C)`

B

`h_(A)gth_(C),K_(C)gtK_(A)`

C

`h_(A)=h_(C),K_(B)=K_(C)`

D

`h_(A)lth_(C),K_(B)gtK_(C)`
