For a simple harmonic motion energy is given with:
Where k is a constant that depends on the type of the wave you are looking at and A is amplitude.
Let's calculate the energy of the wave using two different amplitudes given in the problem:
We can see that energy associated with the wave is 4 times smaller when we decrease its amplitude by half. So the answer should be C.

Answer:
The correct option is (a).
Explanation:
We know that, the E is inversely proportional to the distance as follows :
We can write it as follows :
Put all the values,
So, the correct option is (a).
