\( A \) is singing a note and at the same time \( B \) is singing a note with exactly one-eighth the frequency of the note of \( A \). The energies of two sounds are equal, the amplitude of the note of \( B \) is
[NCERT 1981; AIIMS 2001]
\( \mathrm{P} \)
(a) Same that of \( A \)
(b) Twice as that of \( A \)
(c) Four times as that of \( A \)
(d) Eight times as that of \( A \)
