A stone falls freely under gravity . It covers distances `h_1` `h_2` and `h_3` in the first 5 seconds , the next 5 seconds and the next 5 seconds respectively . The relation between `h_1` , `h_2` and `h_3` is:

A

`h_1 = 2h_2 = 3h_3`

B

`h_1 = (h_2)/3 = (h_2)/5`

C

`h_2 = 3h_1 and h_3 = 3h_2`

D

`h_1= h_2=h_3`
