The correct answer is: A. Page : Book
A letter is a single unit of a written language, while a word is a group of letters that form a unit of meaning. A page is a single sheet of paper in a book, while a book is a collection of pages bound together.
The other options are not correct because:
- A product is not necessarily made in a factory. For example, a product can be made by hand or in a small workshop.
- A club is not necessarily made up of people. For example, a club can be made up of animals or objects.
- Homework is not necessarily done in school. For example, homework can be done at home or at a library.
