A number of bullets are fired in all possible directions with the same initial velocity \( \mathrm{u} \). The maximum area of ground covered by bullets is :-
(1) \( \pi\left(\frac{2 u^{2}}{g}\right)^{2} \)
(2) \( 3 \pi\left(\frac{u}{g}\right)^{2} \)
(3) \( 5 \pi\left(\frac{u}{2 g}\right)^{2} \)
(4) \( \pi\left(\frac{u^{2}}{g}\right)^{2} \)
\( \mathrm{P} \)
