I believe the answer is A. Hope I helped :)
B.One if his sisters would have a strong outburst of emotion
Here, the second sentence is "<span>The Hubble telescope has captured many amazing images from outer space" we can exclude it , in order to condense the paragraph.
In short, Your Answer would be Option B
Hope this helps!</span>
The subject would be "the ball." The subject in the sentence is the person, place, or thing. In this case the ball would be the subject because it's the most mentioned in the sentence, and also it's the first thing that comes into mind when your reading the sentence, the BALL hits a goal post and then the BALL bounced off.
Hope this helps!
