Correct Option - 3

Detailed Solution:

Root mean square speed of gas molecules

$ν_{rms} = \sqrt[]{\frac{3 R T}{M}}$

Pressure exerted by ideal Gas

$P = \frac{1}{3} ρ v_{r m s}^{2}$

$P = \frac{1}{3} m n ν^{2}$

$ρ = m n, v_{r m s}^{2} = ν^{- 2}$

Average kinetic energy of a molecular

$K E = \frac{3}{2} K T$

Total internal energy of 1 mole of a diatomic gas

$U = \frac{f}{2} μ R T$

$U = \frac{5}{2} R T$ (For 1 mole diatomic gas)
