Answer:
The statement that correctly explains the way the image and the text work together is:
B) The image shows the speed and motion of the nuclei, and the text explains why they fuse.
Step-by-step explanation:
Even though you did not post the picture, you described what is in it. I also found it online, which allows me to answer this question safely.
The picture is basically showing us the nuclei and the way they move. The wispy tails behind them serve to imply great speed. We can also see, from the way they are disposed, that the nuclei move in different directions.
The passage, in its turn, serves to explain how and why they fuse. The nuclei, in their frenzy, end up colliding, slamming into one another. They fuse when they push through other nuclei's force fields.
Note: I tried to upload the picture, but some error prevented me to.
