Which one of the following relations for three types of velocities is true for oxygen gas at 300 K?
(where ⟨c²⟩^½ = root mean square velocity; ⟨c⟩ = average velocity; c_p = most probable velocity)

1. (a) ⟨c²⟩^½ > c_p > ⟨c⟩
2. (b) ⟨c⟩ > c_p > ⟨c²⟩^½
3. (c) ⟨c²⟩^½ > ⟨c⟩ > c_p
4. (d) ⟨c⟩ > ⟨c²⟩^½ > c_p
