Which option is an example of paraphrasing done correctly?

I believe paraphrasing done correctly would be OPTION B because it is giving credit to the author.

A) By 1926, Goddard had constructed and successfully tested the first rocket using liquid fuel. Indeed, the flight of Goddard’s rocket on March 16, 1926, at Auburn, Massachusetts, was as significant to history as that of the Wright brothers at Kitty Hawk.

B) The Civil War tore apart the nation as states fought one another from 1861 to 1865. When the war ended, 750,000 Americans had died, and 4 million people had been freed from slavery. Despite the costs, the war kept the states together as a country and redefined the nation. (National Park Service 2018)
