The Correct Option is A
Solution and Explanation
The kinetic energy of gas molecules at a given temperature is given by:
\[ KE = \frac{f}{2}kT \]
where \( f \) is the degrees of freedom and \( kT \) is the thermal energy term.
This is a conceptual fact based on the equipartition theorem, which states that all gases at a given temperature have the same average kinetic energy per molecule.
