Let $\theta$ be angle of elevation of sun. Given that: angle of elevation is $60^\circ$from tower of foot and distanceBC=100 meters. Here, we have to find the height of tower. So we use trigonometric ratios. In a triangle ABC $\Rightarrow$ tan C=( AB)/(BC) $\Rightarrow$ tan $60^\circ$= (AB)/(BC) $\Rightarrow$ sqrt 3=h/100 $\Rightarrow$=100sqrt3 Hence correct option is a.
