From the top of a tower, 80 m high from the ground, a stone is thrown in the horizontal direction with a velocity of `8ms^(-1)`. The stone reaches the ground after a time 't' and falls at a distance of 'd' from the foot of the tower.
Assuming `g=10ms^(-2)`, the time t and distance d are given respectively by

Options

A. 6 s, 64 m
B. 6 s, 48 m
C. 4 s, 32 m
D. 4 s, 16 m
