The correct answer is C. It is written by an expert on the book's subject

Explanation:

In writing, a foreword is a type of introduction to a book or literary work, this differs from regular introductions because these usually are not written by the author of the paper, but by someone different who is usually an expert in the subject or an author of a similar paper who has some relation or link with the author of the paper. Additionally to this, forewords are mainly short and are usually the first content of a book or paper. This type of entry is used to show the audience the credibility of the work as it has been approved by others. Considering this, the feature that distinguishes the passage as foreword is that "It is written by an expert on the book's subject" considering only forewords are written by someone different to the author and this is clearly state in the passage as the author uses "I" to refer to himself or herself and then uses the name of the author of the paper "Ana Ramon" to make clear he or she is not the author but approves the work of her work.
