1 point safety

[Kirby]

With no books by my side here's my guess at what options A has

(1) Decline the illegal kick and take the results of the play which is a safety (1 point). The ball will be free kicked from the K40.
(2) Accept the penalty half the distance to the goalline from the basic spot (not specified in the original post) and re-try.
(3) Accept the results of the play (1 point safety) and enforce the 15-yard illegal kicking penalty from the succeeding spot. A will free kick from the B45.
