The correct answer is C) the number one
Explanation:
The purpose of note cards is to register key information about sources such as articles, books, research studies, among others; this is useful if you are writing a research paper and need to use multiple sources. Additionally, note cards have a specific structure; this includes the topic, which is placed in the upper left-hand corner of the card; the number of the source, which is placed in the upper right-hand corner of the card; and a quotation or paraphrase, which is the main content of the card.
According to this structure, the information that should be entered at the upper right-hand corner of the card is the source number, which in this case is number 1 as this is the number assigned to the source "Human Cloning and Genetic Modification", you can see this in the information about the source as number one appears in the upper right-hand corner.
