The speed of sound through oxygen at \( \mathrm{T} \mathrm{K} \) is \( (300 \mathrm{~m} / \mathrm{s}) \). When the temperature is increased to \( 3 \mathrm{~T} \), the molecule dissociates into oxygen atom, now the speed of sound
\( P \) will be
(A) \( 520 \mathrm{~m} / \mathrm{s} \)
(B) \( 801 \mathrm{~m} / \mathrm{s} \)
W.
(C) \( 600 \mathrm{~m} / \mathrm{s} \)
(D) \( 580 \mathrm{~m} / \mathrm{s} \)
