Out of all the given choices, the name of Stephen King’s first novel is letter A or Carrie. It was published in April 1974 and covers the story of Carrie White, a misfit high school girl who discovered that she had powers to move objects using her mind. It was best known because of its scene during Carrie’s senior prom wherein she confronted everyone who made fun of her and eventually killed a lot of people.
Some people would probably say that Stephen King’s first work is not Carrie but The Glass Floor or Surf Night. Although the Glass Floor and Surf Night were published in 1967 and 1969 respectively, it is worthy to note that these two were short stories and not really considered as novels.
