Pick out correct statement among the following about the equal volume of ${\mathrm{N}}_2\left(g\right)$ and ${\mathrm{O}}_2\left(g\right)$ at 298K and 1 $\mathrm{atm}$:

The average translational kinetic energy per molecule is same of ${\mathrm{N}}_2\left(g\right)$ and ${\mathrm{O}}_2\left(g\right)$

The most probable speed of two gases is same

The total translational kinetic energy of ${\mathrm{N}}_2\left(g\right)$ and ${\mathrm{O}}_2\left(g\right)$ is same

Both (a) and (c)
