Answer:
sketchbook
Step-by-step explanation:
The most appropriate choice is d, sketchbook. This is because the description above mentions that the book purchased by Joanie's sister is often used to store creative visual and written materials in one place. A sketchbook is a type of book that is suitable for this purpose as it is specifically designed for drawing or sketching but can also be used for writing and recording creative ideas. In contrast, option a, musical book, is not relevant as there is no mention of any connection to music. Option b, comic book, is more specific to a certain type of illustrated storybook. Option c, a camera, may be used for the same purpose but does not include the ability to write or record written ideas.
