I believe the answer is idiom, the phrase is not comparing anything so simile and metaphor is out of the question, also personification is giving a non living thing human characteristics.
The correct answer is A. I hope I helped! (o´∀`o)
Answer:
C. Both were self-educated
Explanation:
I found online that said, "Douglass’ story illustrates how even self-directed education can lead to personal and social transformation..." (The Self-Education of Frederick Douglass, July 9, 2019 by Chris Gehrz)
I also found online that said, "Lincoln’s key to self-educating himself was reading." (Abraham Lincoln’s Self-Education, by Kimbriah Alfrenar)
The things that I bolded show how both men were self-taught, therefore it proves how the answer is C. Both were self-educated.
