Figure shows two small blocks placed on smooth horizontal surface. They start moving from the same line with forces 2F and F respectively acting on the blocks. Their momenta and kinetic energies at the instant of crossing the finishing line as shown in figure are `P_(A), P_(B)` and `K_(A), K_(B)`. Then choose the correct option.

A

`K_(A)=K_(B),P_(A)=P_(B)`

B

`K_(A)gtK_(B),P_(A)gtP_(B)`

C

`K_(A)gtK_(B),P_(A)ltP_(B)`

D

`K_(A)gtK_(B),P_(A)=P_(B)`
