Thermodynamics Part 3

Because $KE \propto T$ so $A$ is correct, $B$ is incorrect, statement $C$ cannot be said, statement $D$ is contradicting itself, statement $E$ is incorrect (Isothermal process)So no answer correct (Bonus)If the statement of $D$ would have been."Pressure of gas increases with increase in temperature at constant volume, "then statement $D$ would have been correct, so in that case answer would have been 'A'.
