$A$ is singing a note and at the same time $B$ is singing a note with exactly one-eight the frequency of the note of $A.$ The energies of two sounds are equal, the amplitude of the note of $B$ is

(d) Energy $\propto a^{2}n^{2} \Rightarrow \frac{a_{B}}{a_{A}} = \frac{n_{A}}{n_{B}}\ \ \ \lbrack\because energy\ is\ same\rbrack$
$\Rightarrow \frac{a_{B}}{a_{A}} = \frac{8}{1}$
