Answer: The book Nano Nukes
Explanation: A copyright is a legal type of protection given to the author that states that only the author can decide how others can use her work. With a copyright, work can be used only if the author grants them permission to use it. This means that her work cannot be copied, used or performed without her permission.
However a copyright only protects the written expression of the author's work. This means that the only thing that will be copyright protected is what Zoe physically put in her book, unlike a patent, which protects the idea itself, or other forms of intangible protection laws.
