A baloon is moving up in air vertically above a point A on the ground. When it is at a height $h_{1}$ , a girl standing at a distanced (point $B$ ) from $A$ (see figure) sees it at an angle $45^{\circ}$ with respect to the vertical. When the balloon climbs up a further height $h_{2}$ , it is seen at an angle $60^{\circ}$ with respect to the vertical if the gitl moves further by a distance $2.464 \; d$ (point $C$ ). Then the height $h_{2}$ is (given $\tan 30^{\circ}=0.5774$ ) :

Option: 1 $1.464\; d$
Option: 2 $0.732\: d$
Option: 3 $0.464\: d$
Option: 4 $d$
