A stone of mass of \( 16 \mathrm{~kg} \) is attached to a string \( 144 \mathrm{~m} \) long and is whirled in a horizontal circle. The maximum tension the string can withstand is \( 16 \mathrm{~N} \). The maximum velocity of revolution, which can be given to the stone without breaking it, is
(A) \( 20 \mathrm{~m} / \mathrm{s} \)
(B) \( 16 \mathrm{~m} / \mathrm{s} \)
(C) \( 14 \mathrm{~m} / \mathrm{s} \)
(D) \( 12 \mathrm{~m} / \mathrm{s} \)
