#### Solution

Let θ be angle of elevation of sun.

Given that: angle of elevation is `60°`from tower of foot and distance`BC=100` meters.

Here, we have to find the height of tower.

So we use trigonometric ratios.

In a triangle `ABC`

`⇒ tan C=( AB)/(BC)`

`⇒ tan 60°= (AB)/(BC)`

`⇒ sqrt 3=h/100`

`⇒=100sqrt3`

Hence correct option is `a`_{.}
