What would Cersei do if Jon became king?
Who do you think would be the biggest opponent to Jon becoming king?
It's hard to say who Jon's biggest opponent would be, as there are many people who could potentially stand in his way. Cersei would certainly be a major obstacle, but there are also other powerful families in Westeros who might try to prevent him from taking the throne. The Lannisters, for example, may not be the only ones who feel threatened by Jon's claim to the throne. There's also the possibility that some of the Northern lords might oppose Jon's rule, given that he's not a "true" Stark.
