Three different objects of masses `m_(1) , m_(2)` and `m_(2)` are allowed to fall from rest and from the same point `O` along three different frictionless paths. The speeds of three objects on reaching the ground will be:
A. `m_(1) : m_(2) : m_(3)`
B. `m_(1) : 2m_(2) : 3m_(3)`
C. `1:1:1`
D. `(1)/(m_(1)):(1)/(m_(2)):(1)/(m_(3))`
