Identify the correct labels of $\mathrm{A},\mathrm{}\mathrm{B}$ and $\mathrm{C}$ in the following graph from the options given below:

Root mean square speed $\left({\mathrm{V}}_{\mathrm{r}\mathrm{m}\mathrm{s}}\right);$ most proable speed $\left({\mathrm{V}}_{\mathrm{m}\mathrm{p}}\right);$ Average speed $\left({\mathrm{V}}_{\mathrm{a}\mathrm{v}}\right)$

• A

  $\text{A}-{\text{V}}_{\text{mp}};\text{B}-{\text{V}}_{\text{rms}};\text{C}-{\text{V}}_{\text{av}}$
• B

  $\text{A}-{\text{V}}_{\text{av}};\text{B}-{\text{V}}_{\text{rms}};\text{C}-{\text{V}}_{\text{mp}}$
• C

  $\mathrm{A}-{\text{V}}_{\text{rms}};\text{B}-{\text{V}}_{\text{mp}};\text{C}-{\text{V}}_{\text{av}}$
• Correct answer
  D

  $\text{A}-{\text{V}}_{\text{mp}};\text{B}-{\text{V}}_{\text{av}};\text{C}-{\text{V}}_{\text{rms}}$

Hence, the correct answer is option: 'D'.
