A flagstaff of length \( I \) is fixed on the top of a tower of height \( h \). The angles of elevation of the top and bottom of the flagstaff at a point on the ground are
\( \mathrm{P} \) \( 60^{\circ} \) and \( 30^{\circ} \) respectively. Then

W
(A) \( \quad \mathrm{l}=2 \mathrm{~h} \)
(B) \( 2 \mathrm{l}=\mathrm{h} \)
(C) \( \quad 1=3 \mathrm{~h} \)
(D) \( 3 \mid=h \)
