What is true regarding the tallest flyer when utilizing a skysled?

The statement that the tallest flyer must be the ripcord puller is correct because the configuration of the skysled requires that the person who pulls the ripcord—the mechanism that initiates the launch—should be positioned in a way that allows them to effectively reach and operate the pull cord. Typically, this person is selected based on their height and reach; the tallest flyer generally has the advantage of being able to pull the cord easily while also ensuring that they are harnessed securely.

If there were other configurations or considerations, it's vital to prioritize safety and ensure maximum efficacy in the operation of the skysled, which the tallest person often fulfills by being the ripcord puller. The other options might suggest arranging based on different characteristics, but they do not align with the operational requirements of the skysled.
