A bus is beginning to move with an acceleration of \( 1 \mathrm{~m} / \mathrm{s}^{2} \). A boy who is \( 48 \mathrm{~m} \) behind the bus starts running at \( 10 \mathrm{~m} / \mathrm{s} \). The time(s) at which the boy can cafch the bus :
(A) \( 8 \mathrm{~s} \)
(B) \( 10 \mathrm{~s} \)
(C) \( 12 \mathrm{~s} \)
(D) \( 14 \mathrm{~s} \).
