As long as all the waves stay in the same medium, the intensity of

changes to 1/3² or 1/9 of the original intensity.
I suppose choice-'d' is the correct one, but I have to tell you that
the phrase "nine times as low" is mathematically meaningless,
and it really grinds my gears.
Answer:
Explanation:
Given
Mass of solid uniform disk 
radius of disk 
mass of lump 
distance of lump from axis 
Moment of inertia is the distribution of mass from the axis of rotation
Initial moment of inertia of disk 
Final moment of inertia 
=Moment of inertia of disk+moment of inertia of lump about axis
