A Correct answer
Explanation

Edison's most prolific and impactful invention in 1878 was the incandescent light bulb, which he developed commercially after years of experimentation. While he did not invent the first light bulb, his 1879 patent created the first practical, long-lasting bulb for commercial use. The other options (hoset?, micro chip, electric fan) are either nonsensical or anachronistic.
