Interception in endzone

[maven]

Safety. 8-5-2c

If you look up the rule, you'll need to revise your use of the term 'offense'. In rule book terminology, the offense is the team in possession. 2-43-1

So it's better to state your case using A and B: B intercepts in the EZ and holds there, running it back for a TD. A will have the option to accept the penalty (safety, 2 points for A and B will free kick from their 20YL) or decline it (TD for B).
