The correct answer is D. Shelley was an introverted child who spent much of her time wandering the countryside
Explanation:
Mary Shelley who is mainly known for being the author of the novel "Frankenstein" was an English novelist during the 19th century. During her childhood, Mary Shelley grew up without his mother as she died after Shelley was born due to puerperal fever, instead her father and sister were in charge of growing up Mary. In general terms, despite the absence of her mother, the childhood of Shelley was rather happy, but after her father married again and Mary was not sent to school she started spending time reading from her father library and writing stories and poems outside of the house while wandering and staying in the countryside. Thus, even when Mary was not a neglected child during the first years of her life she was mainly introvert as she focused on reading and writing mostly in the countryside rather than playing with other kids.
