Flagrant1 penalty

[the girl ref]

I think I am probably over thinking this one:

A1, while in possession of the ball, begins her try. During A1 try and before the ball is released, B2 illegally pushes through A2's screen to defend A1 and is whistled for a foul. A1 continues her try and the ball enters the basket.

a.The goal is cancelled and A1 is awarded two free throws.
b.The goal is scored and A2 is awarded a one-and-one bonus.
c.The goal is cancelled and A2 is awarded a one-and-one bonus.
d.The goal is scored and A1 is awarded one free throw.

I have ruled out b & c because nowhere in the question does it state that team A is in the bonus. Also, while it states that B2 illegally pushes through the screen of A2, it also states she is defending A1 and called for foul- to me I think that she fouls A1 while in the act of shooting--- so the goal shall count and should get 1 free throw....

my thought process correct??
