Hint: The anode rays are negatively charged ions which are produced due to the very high voltage being applied. Due to this high voltage, the atoms break down into ions.
Complete Step by Step Solution:
The anode rays are created due to the gas present in the tube. Due to the high voltage being applied, the atoms break. They break into either positively charged ions called anode or negatively charged ions called cathode. The charge to mass ratio of an object is the ratio of the charge and mass of the same object.
Now if there are different gases, they will be producing different amounts of anode rays as different gases have different mass and charges. Steam is also a factor which affects the charge-to-mass ratio. So, for anode rays, it gets changed and is not constant. It can be said that the charge-to-mass ratio of the particles in anode rays depends on the gas present in the tube.
Hence, Option A is the correct answer.
Note: It is important to remember that the charge to mass ratio for cathode rays is constant, unlike anode rays. It does not change. If in an electric field, it is the anode rays that are affected and show deflection in a direction opposite to the direction of deflection of the cathode rays. The charge to mass ratio is a quantity which is of great importance in tracing the path of particles like electrons, protons etc when placed in electric or magnetic fields.
