A particle of mass \( \mathrm{m} \) is projected with a velocity \( u \) making an angle of \( 30^{\circ} \) with the horizontal. The magnitude of angular momentum of the projectile about the point of projection when the particle is at its maximum height \( h \) is
(a) \( \frac{\sqrt{3}}{2} \frac{m v^{2}}{g} \)
(b) zero
(c) \( \frac{m v^{3}}{\sqrt{2} g} \)
(d) \( \frac{\sqrt{3}}{16} \frac{m v^{3}}{g} \)
