In a Functional Analysis (FA), the control is meant to show a participant free from the possible functions of behavior (access, escape, automatic). In essence, you want to "control" for those by removing them, so you'd want to give the participant no need to engage in behavior controlled by a matching function. In order to do so, the participant should have non-contingent access to preferred items, attention, and escape from aversive conditions, answer 2.
