The displacement-time graph for two particle \( A \) and \( B \) are straight lines inclined at angles of \( 30^{\circ} \) and \( 90^{\circ} \) with the time axis. The ratio of the velocities \( V_{A} \) and \( V_{B} \) is :
(A) \( 1: 2 \)
(B) \( 1: \sqrt{3} \)
Figure \( 1.117 \)
(C) \( \sqrt{3}: 1 \)
(D) \( 1: 3 \)
