Stumping you chumps question of the day

[ljudge]

#1) I have the same ruling in both A and B. That is, enforce the foul as during "loose ball play" and give K a first down or accept the result of the play and enforce the foul from the succeeding spot. In B I have PSK not being applied since K was in possession of the ball at the end of the play.

#2)
a - false - 7.2.3, 7.2.5a
b - true - 7.2.2
c - false - 9.4.5
d - true - 7.5.6.a
