What type of restart occurs when the attacking team kicks the ball out the back of the defending teams in-goal?

[jdeagro]

If the attacking team kicks the ball (punt in the air or grubber on the ground - I assume no difference here) and it does not touch a defending player, and goes out the back of the defending team's in-goal, what type of restart occurs? In-Goal dropout, 22m dropout, scrum option, something else? A citing on the relevant law would be appreciated. Thank you!

Option: 22 Drop out or scrum where ball was kicked.

Law 21.11:

If a team kicks the ball through their opponents’ in-goal from the field of play into touch-in-goal or on or over the dead-ball line, the defending team can choose:

1. To have a drop-out anywhere on or behind the 22-metre line; or
2. To have a scrum at the place where the ball was kicked.

Exception: An unsuccessful kick at goal or attempted dropped goal. In these cases, the defending team restarts with a 22-metre drop-out.

Thank you! You're a gentleman and a scholar! I was initially looking under Law 12 for it but I guess it makes more sense under 21.
