Dear Student,

If damping is ignored then the amplitude of te ripples will remain the same. i.e. 4cm .

I think the above answer is wrong.
Simply imagine a light bulb emitting light. The further you go, the dimmer it appears.
So, intensity decreases further you go from the source.
Now, since intensity is proportional to ampletude, even if damping is ignored, the ampletude would decrease.
And you don’t need an IITian to do that. Irritating adds..
