The 21-year-old, who has scored 41 goals for the Scottish outfit this season, is widely expected to complete a move to the former Scottish Premier League side at the end of the season.
"Ally McCoist has said there is a wee bit of interest and has spoken to my dad and my agent. I've not spoken to him yet but we'll see what happens over the next couple of weeks and, hopefully, something can get done," Clark told reporters at a press conference.
"Rangers are the best club in Scotland in my eyes so I'd find it hard to say no to them. There are a few clubs down south interested so I need to weigh up my options but if Rangers say they want to sign you, you can't get much better than that."
Clark was handed the PFA Scotland Second Division Player of the Year Award this season.
