If defense commits pass interfernce in endzone but catch is compleated and penalty is declined but later reversed on challange can the penalty be reassisted?

Answer 1

The challenge comes before any penalty is assessed. That is due to the fact that, in your question, the offense would not know whether to accept the penalty if they don't know what the outcome of the play is. So what would happen would be A) the referee will accept the other team's challenge, B) make a ruling to the final outcome of the play after looking at the replay (completed or incompleted pass), and then the offense will decide whether or not to accept the penalty.
