Certain amount of an ideal gas is taken from its initial state 1 to final state 4 through the paths \(1 \rightarrow 2 \rightarrow 3 \rightarrow 4\) as shown in figure. \(A B, C D, E F\) are all isotherms. If \(v_p\) is the most probable speed of the molecules, then

- A \(v_p\) at \(3=v_p\) at \(4>v_p\) at \(2>v_p\) at 1
- B \(v_p\) at \(3>v_p\) at \(1>v_p\) at \(2>v_p\) at 4
- C \(v_p\) at \(3>v_p\) at \(2>v_p\) at \(4>v_p\) at 1
- D \(v_p\) at \(2=v_p\) at \(3>v_p\) at \(1>v_p\) at 4
