Solution

The correct option is A the stone files off tangentially
Until the stone is tied to a string, due to tension in string, it have centripetal force and centrifugal force along in radial direction of motion so when the rope breaks, it doesn't have force in radial direction so due to inertia the stones flies off tangentially.
