After the U.S. Department of Transportation issued a new regulation allowing automakers to opt out of federal airbag requirements for certain vehicle models, the state of Idaho filed suit in federal court seeking to enjoin the regulation as a violation of the federal Administrative Procedure Act. Idaho's complaint alleges that the state will incur millions of dollars in additional medical costs if the rule is allowed to go into effect. In response, lawyers for the agency filed a motion to dismiss the suit, arguing that Idaho lacks Article III standing. A reviewing court is most likely to:
a) Grant the motion, as Idaho's injury is speculative and not concrete
b) Deny the motion, as Idaho has a sufficient stake in the controversy
c) Suspend the case until the regulation takes effect
d) Dismiss the case, as the court lacks subject matter jurisdiction
