At some point of time, when a motor car is travelling at \( 30 \mathrm{~m} / \mathrm{s} \) on a circular road of radius \( 500 \mathrm{~m} \). If it is increasing speed at the rate of \( 2 \mathrm{~m} / \mathrm{s} \). The acceleration is
(A) \( 2.7 \mathrm{~m} / \mathrm{s} \)
(B) \( 2.5 \mathrm{~m} / \mathrm{s} \)
(C) \( 2.9 \mathrm{~m} / \mathrm{s} \)
(D) \( 2.3 \mathrm{~m} / \mathrm{s} \)
