Certain amount of an ideal gas is taken from its initial state 1 to final state through the paths `1 rarr 2 rarr 3 rarr4` as shown in figure, AB, CD, EF are all isotherms. If `v_p` is the most probable speed of the molecules, then

A

`v_p " at " 3 = v_p " at " 4 gt v_p " at " 2 gt v_p " at " 1`

B

`v_p " at " 3 gt v_p " at " 1 gt v_p " at " 2 gt v_p " at " 4`

C

`v_p " at " 3 gt v_p " at " 2 gt v_p " at " 4 gt v_p " at " 2`

D

`v_p " at " 2 = v_p " at " 3 gt v_p " at " 1 gt v_p " at " 4`
