Solution

The correct option is D None
Let ′h′ be height of each storey of building using $s = u t + \frac{1}{2} a t^{2}$
$16 h = 0 \times 4 + \frac{1}{2} \times 10 \times 4^{2}$
$h = 5.25 \frac{m}{s}$
Distance covered in 1st second
$s_{n} = u + g (n - \frac{1}{2})$
$= 0 + 10 (1 - \frac{1}{2})$
$= 5$
