PLEASE HELP! I WILL MARK BRAINLIEST! Which detail from "Thomas Edison: The Master of Improvement” supports the big-picture idea of the passage?

O Humphry Davy created the first electric light and shared his design with Edison.

O Unlike Davy and Swan, Edison had no formal schooling. He was quite sickly as a child, so his mom taught him at home.

O That way, all of those long-lasting Edison bulbs would have a ready supply of the electricity they required.

O Edison was successful because he persevered through challenges to reach his goal of creating a practical lightbulb.
