Answer & Explanation Answer: D) The characteristics of cathode rays depend upon the nature of the gas present in the cathode-ray tube.

Explanation:

Cathode ray is a beam of electrons emitted from the cathode of a vacuum tube. It is invisible. Cathode ray tubes are also found in televisions and computer monitors. Since cathode ray is a beam of electrons and all electrons are identical, charge to mass ratio is same for all the gases and does not depend on the nature of gas.
