Which of the following statement(s) is(are) correct regarding the root mean square speed (U_\text{rms}) of a molecule in a gas at equilibrium? [JEE Adv 2019 P1]

\epsilon_\av at a given temperature does not depend on its molecular mass

U_\rms is inversely proportional to the square root of its molecular mass

U_\rms is doubled when its temperature is increased four times

\epsilon_\av is doubled when its temperature is increased four times
