Separate a Category I aircraft departing on the same runway from an intersection behind a preceding departing Category G aircraft by ensuring that it does NOT start takeoff roll until ___ minutes after the large aircraft has ___.

Explanation:
Wake turbulence from a heavier aircraft can persist in the takeoff path after the departure, so a following aircraft must wait a safe interval before starting its own takeoff roll. The right rule here is to hold the following Category I for 3 minutes after the preceding Category G aircraft has rotated or taken off. This covers both moments when hazardous vortices can be shed: during rotation and once the heavy is airborne. Other options either use too short a delay or count only one event, which could leave the following aircraft still at risk of encountering lingering wake. So, three minutes after the large aircraft has rotated or taken off is the correct requirement.
