A) The    cathode    rays    originate    from cathode   and   proceed   towards   the anode   in   a   cathode-ray   discharge tube. B) The television picture tubes are nothing but cathode ray tubes.
C) The  cathode  rays  themselves  are  not visible. D) The   characteristics   of   cathode   rays depend  upon  the  nature  of  the  gas present in the cathode-ray tube.
 
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.
