A particle moves in a straight line. The displacement \( x \) of the particle varies with time as \( x=2-5 t+6 t^{2} \). Then the initial velocity of the particle is:
(A) \( 2 \mathrm{~m} / \mathrm{s} \)
(B) \( -5 \mathrm{~m} / \mathrm{s} \)
(C) \( 6 \mathrm{~m} / \mathrm{s} \)
(D) \( -3 \mathrm{~m} / \mathrm{s} \)
