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.
