Answer;

37 ° C

Explanation;

-The average kinetic energy of gas particles is directly proportional to the the temperature. An increase in temperature increases the speed at which the gas molecules move, and thus increasing their kinetic energy. At any given temperature gases have the same kinetic energy.

-Hence, the temperature at which Helium gas will have the highest kinetic energy is at the highest temperature, which is 37° Celsius.
